Just snaged a 5850 on the MM, crossfire with uber clocking 5830?

Access to the Members Market forum requires two things. Firstly, you will need to have over 250 posts and have been signed up for at least 90 days. Please note that this does not mean you spam the forums simply to increase your posts, as this action will result in posts being deducted, and if you continue this behaviour, your account will eventually be banned/suspended. Once you reach 250 posts, you will need to activate your trust. This is either found in your UserCP, or you can press the trust button that appears at the bottom of all your posts.

Once you satisfy both of these criteria, Members Market access will be granted within 24hrs. Please do not post on the forums asking why you cannot access the members market, if you have any queries, email one of the forum Dons/Admins. The contact addresses are available in the FAQ.

I don't understand the hating of the 5830 and this talk of it being overpriced? The 5770 seems to be £120-£150, the 5830 £165-£185 (unless you buy from OCUK), and the 5850 is £225-£300. Seems pretty middle ground to me.

The only wierd thing I can see about it is the power usage, this review comments on the wierd bits of the 5830.

It uses 25W more than the 5850 at full chat, but it's slightly slower. This is explained in the review though.

When you look at the benchmarks, you see that it's actually very close to the 5850.

3DMark Vantage Perf:
5770-10,963
5830-14,042
5850-14,416

3DMark Vantage High
5770-6,807
5830-8,968
5850-9,605

3DMarkVantage Extreme
5770-4,661
5830-6,043
5850-6,579

As you can see in performance terms, much closer to the 5850 than the 5770.

The lowest prices I've found are:

5770 - £120
5830 - £165
5850 - £240

So the performance is closer to a 5850, yet the price is closer to a 5770. Obviously this info that I've found could all be wrong, but based on this I can't see the issue?

EDIT: Just noticed that they say that it's closer to the 5770 in performance stakes. But from those results I can't see the £75 price jump to the 5850?

At 165 it's much better...when it first came out it was really not far off the cost of a 5850 which didn't make much sense. Also I think we were all hoping for 24 ROPs which would have made the card a lot more attractive.

I agree that it's still pretty good though....
 
I've noticed that on OCUK they're £200 at the cheapest. No idea why that is, but I think I'm going for a 5830 now. The 5770 seems good for me but a little bit on the weedy side, and the 5850 is too expensive.

Benchmarks yes, but in actual games it is trailing the 5850 by quite a bit. Depends on the title. Some say it's down to the ROPS being halved from 32 to 16 as it has the same memory bandwidth, but can't get as high a render throughput. Perhaps it will be closer to the 5850 in newer titles.

I own a 5830 and it is closer to a 5770 in games than a 5850 when at stock 800Mhz. However, overclock it to at least 870 and it trails the 5850 by about 10 FPS at all resolutions. Get it up to 950 like mine is running and it's getting very close. I think ATI made an error - these cards should have been at least 850, ideally 875 stock speeds.

Do a volt mod and push it past 1000 and push the memory to say 1200 and you are getting pretty much 5850 performance, not quite in all situations however. It seems to gain more from core clocking than memory clocking.

At 800Mhz, a fair price for this card is £150-160.

I just ordered it, £172 inc postage. It's actually 825mhz.

I'm not really into overclocking any more, I tend to just run everything at stock now. It'll provide a big step up from my 4670, it'll look manly in my case. (Should fit with literally millimeters to spare), and it was roughly £75 cheaper than a 5850, so I think I've made the right choice. :P
 
Muel, you will be very happy with the performance jump. It's BIG.

I have the Powercolor one and it runs very cool and quiet as it has the same 4 heatpipe cooler and VRM heatsink as the 5870.
 
That's the one I ordered, the PowerColor HD5830 OC?

It's 257mm long, and my case has roughly 270mm of space. Might require some chopping out of the HDD bays. :P

I think my PSU will JUST about do... Corsair TX650W?
 
I could, but my board can only CF at PCIEx8. :(

What I will also be adding though is a nasty cheap PCIE card (a £15 jobby), just to run a third monitor in windows (only tempory, I'll be taking the third away with me to uni). I'll also be getting a Freeview card at some point I think.
 
Agree, PSU fine.

I think you might be out of space however. Just measured the card - it's 27cm long, same as my old GTX 280, but the PCI-E connectors are in a silly position - on the end of the card. So you will need 30cm total clearance to be comfortable. :(
 
Assuming the board is x8 2.0 then performance will barely be affected. My board only does CF/SLI @ x8 2.0 and the performance is great.
 
Hehehehe, this is gonna get fun!

My plan is to remove the HDD bays and elastic mount my HDDs in the 2 remaining optical bays. They won't be cooled though...

The other option is to move the HDDs to the bottom, and chop the top half of the HDD cage off.

This is in an Antec 300 by the way.

I'm not sure tbh, it's a Asus M4A78XDT EVO. I doubt I'll go CF really, I only game on one monitor at 1920x1200, so doubt it'd really needed.
 
Oh well, good luck Muel! :)

I have my HDD down at the bottom of the case to allow clearance, but it's my dedicated gaming rig so only has one HDD and one optical drive. Plenty of room to shove things in the cage area, so I managed to get it in there. CF would be a struggle!
 
I think what I need to find out is if these hard drives really need cooling, because if not I can suspend them in the optical bays and cut out a bit more noise at the same time.

My main HDD is a Samsung F1 320gb, the second is a Samsung F3 1TB. Neither are the green ones either, I suppose I could just move them and trying benching them and see what kinda temp they max at...
