Can a second 5970 fit on my motherboard?

isn't one 5970 good enough for any game out nowadays ?

Not for 2560 res with the eye candy cranked up.

Nice present by the way and will go well in his system as he has a top spec so far

Side fan will help get cool air into the cards, would probably be best off putting it the slot further down like drunkenmaster said as it will help the top card a lot
 
I don't think LauraJ is concerned about if 5970 quad fire is value for money or "the best GPU setup", I think she just wants to make sure it will work for her partner.

If your partner isn't planning to upgrade his graphics for a long time he will certainly enjoy 5970 quad fire especially on a 30" monitor.

Nice gift for him tbh!

Agreed...

And I think you should be fine. I have two GTX480s (which pump out at least as much heat as the 5970) right next to each other in the case, just as you will have. When I'm gaming, the fan speed on the top card spins up quite high (often over 80% fan speed), but there are no real issues beyond that. The card is designed to take cool air in from the end of the card, and dump it out the rear of the case, so the tiny gap between the two cards is not as big a deal as you might think.

Anyway, your fella is a very lucky guy!


edit: I'm not sure a side-fan would make a huge difference, for two reasons. Firstly, as I mentioned above, the main airflow mechanism is the dragging in of cool air from the front end of the card, over the heatsink, and out the rear (right-to-left as you look at it in the case). A side fan would not aid this mechanism. Secondly, there will not be enough of a gap between the cards for the side-fan to generate airflow to cool the heatsink of the top card. You can try it, but I suspect it will make little to no difference to temperatures.

Thanks PaulyD & Duff-Man :) So if we did shove the card into the 8x slot instead of the squeeze of the 16x one, it wouldn't make much difference then? Even though we wouldn't overclock the card?

At least now I know that if we wanted to we could shove the second card into the 16x slot on the motherboard (GA-EX58-UD5). As when I looked at it last night I thought there was no chance! :D


You would have thought that Gigabyte would have swapped the 8x and the 16x around (if they could) saving a lot of problems! Easy to put in and lots of air to get around them! Maybe I should change jobs and teach them a thing or two. Or maybe not... :D

Well he says it isn't as he can't run some games at full settings! :D (and he uses high end graphics software too).

I'm not sure of which model it is, but it's a "Antec" one. I presume it's the latest one they have out. It has three front fans. ;)

Would a side fan help with cooling though?

as for metro2033, it is a pain in the ass for graphic to run, and the game favour nvidia's card (i.e. gtx470/gtx480) more than the ati5000 series. a pair of gtx480 in sli would probably deliver better frame rate a crossfiring a pair of 5970 at 1920x1200 4xaa:
http://www.techpowerup.com/reviews/nvidia/geforce_gtx_480_sli/24.html
They only have a single 5970 there, but assuming the best case scenerio that the frame rate doubling with adding a 2nd 5970 (100% scaling on Quadfire...impossible as it might)...27.4fps x 2=54.8 fps...still behind GTX480SLI's 56.2fps.

With that said, Metro2033 is rare game that is insanely graphic demanding for demanding's sake, and I don't think it's worth spending hundred of pounds on a single game that's only get average score for gameplay from reviews. A single 5970 will max out 99% of the games at 1920x1200 4xAA no problem.

Well worth a try. It will be one more thing for him to play around with and test, which if he's anything like me or the other geeks I know, will only add to the fun :D

And yes - it always amazes me that motherboard manufacturers insist on putting the two x16 slots right next to each other. Perhaps there is some kind of layout reason for it...

It's the second one the Antec 1200. :D

I've heard about the backstabbings of ATI & Nvidia games. If it's ATI gamers moaning that they can't get NVIDIA PhysX, it seems that both companies shove in dodgy codes into their games to cause problems to players with the other manufacturers card. :(

And no, Metro 2033 isn't the only game he's playing! He's also looking out for future games like Crysis 2. :D

So putting it in the 8x slot shouldn't make much difference then?

Maybe they do indeed have to have it in that layout, or more probably to cause problems to gamers in order for them to have to buy the latest model in order for them to get what they want just because the slot is half an inch too close to the other one... :rolleyes:
 
So putting it in the 8x slot shouldn't make much difference then?

Shouldn't make much difference, no. From what I have seen, in most cases the difference is usually just 1% to 2% between PCI-e 16x and 8x. I considered putting my second GTX480 in the 8x slot on my motherboard, but in the end the temperatures and noise with them together were not so bad and didn't affect my overclock (I can get the same as I could with the cards individually), so I kept the original configuration.

The best way will be to try both and see which gives the best results (reduced noise and temperatures vs very slightly improved performance) :)
 
I wish I had a wife like OP who brought me these kind of surprises:(.

Heh - tell me about it! It's a rare breed of woman who:

a) Would consider buying anything at all for her man, outside of birthdays / christmas
b) Knows/cares enough about computer hardware to buy nice new geeky toys!

Do you have a sister by any chance, Laura? :p

Thanks a lot Duff-Man. :) If it really is only 1-2% that really suprises me, from what I've been told in the past I thought it was more like 30%+!

LOL! :D

a) True. But remember, he did take me on a suprise visit to the Seychelles. So it's the least I could do. :D
b) :p

I do indeed, an older one who's a doctor. But sadly she's got a partner & doesn't know much about computers. Sorry! ;)
 
These are results for the GTX480, but since the PCI-e bandwidth required shouldn't change from ATI to nvidia hardware, you can expect something similar:

http://www.tomshardware.co.uk/pcie-geforce-gtx-480-x16-x8-x4,review-31964-16.html

At 16x, adding a second GTX480 gains an extra 63.4% over the single card, but at 8x it gains an extra 59.7%. So, this represents a ~2.3% reduction in overall performance. But it does seem to vary from game to game, so maybe he will enjoy testing out the different configurations in the games he plays the most.


... on a somewhat related note; you can expect the performance gain from adding a second card to be greater at 2560*1600 resolution than at any lower res, as there will be more places where the GPU is the limiting factor (the "bottleneck") than at lower resolutions.

Physx aside, I don't think either ATI or Nvidia can make games run crapper on for their competitor's hardware. Some people might disagree with me, but my personal belief is that the reason why Nvidia cards get more performance than similiar level ATI card in Nvidia games or vice versa is become they invest in providing support for the development of the those particular games while their competitor didn't, and the games are running with increased performance with their hardware, rather than decreasing the performance of the cards of the side that did not work with the developer during the game development process.

My partner has always felt that ATI drivers are never as well made/optimised as Nvidias ones. Supposedly he hasn't been able to install any of the one file (.exe) pack drivers of theirs since May! Every time he does it stops installing half way through. They may pump out a driver each month but what's the point when they don't properly work?! :rolleyes:
 
At the moment he's playing that Metro game (2033?) and he can't crank the highest settings up on that (he's got a [email protected] & 6GB RAM) .Thanks NathWraith! :)
He still won't be able too, even with 2 5970's DoF and Tessellation reduce the game to unplayable rates. Fortunately the game looks stunning without them.

You will need to get hold of a longer crossfire bridge if you intend to use slot 3 (the Crossfire bridge in post 2 is a 100mm bridge), I would assume what you already have is a standard size bridge and so won't be long enough.

That's what I heard from Marine-RX179, it seems that the game is completely optimised for Nvidia cards only. ( http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_480_SLI/24.html )

I would? Great there's always something else that you have to get... :rolleyes: Hopefully, it appears that the card will be coming tomorrow so I'll have a look when putting it in; in mission impossible mode... :p , but annoyingly it now appears I won't get the PSU till the end of the week. :(

So if we wanted to use the third slot (x8) we would need to find a 10cm/100mm bridge? I presume we could get one off ebay etc.?

Just thought there's something else you might need to know. While the 5000 series cards are great for games in general, however it leave something to be desired in the area of tesselation performance if comparing to the Nvidia's GTX470/480 card (which the design heavily focused on tessellation).

Besides Metro2033, there's not really another game that use tessellations like the way it does (yet), and tessellations is not a neccessity and can be disabled like wedgie already pointed out (yes tessellations does make thing look nicer, but the huge impact it has on the frame rate simply not worth it for the HD5000 cards). HD6000 series would hopefully sort out the tessellations weakness of the HD5000 series.

Another thing is that, people is still having doubt of/if heavy use of tessellations for games would ever become mainstream (not just 1 or 2 games).

Laura just to put your mind at ease, if you hav'nt bought the Card and PSU yet.

You will have upto 7 days from delivery to inform the place you buy from, that you want to return, if you want to return that is, and the items can be opened and tested.

You just have to make sure the packaging is'nt damaged, and everything that came with it is still there.

Now im fairly sure this won't happen, as he will be well chuffed like the rest have said, but just wanted to let you know that you can return within 7 days of delivery, even when they have been opened.
