Help with which gtx 670

http://www.overclockers.co.uk/showproduct.php?prodid=GX-190-EA&groupid=701&catid=1914&subcat=2294

I plan on buying 2 for sli and am going to watercool using

http://www.overclockers.co.uk/showproduct.php?prodid=WC-150-XS&groupid=962&catid=1520&subcat=2328

I do eventually want to go 3 monitors but I must admit that I have blown my budget out of the water haha. I can stretch for the latter (4gb) but I guess my question is would it be worth it?

All help will be greatly appreciated. I have a 1000w psu by the way and a z77 sabertooth board. This is my first personal building rig, I have built barebones systems before. This is driving me around the bend regarding gpu. I have up been divided on weather to get 2 or 1 and which one for bout 3 weeks. I have read forums out there so I'm not being "lazy". All opinions and advice would be greatly appreciated.

:)

The 670ftw takes a 680 waterblock/backplate.

1000w power supply could run like 5 or 6 670s it's so overkill!

I believe the verdict btw is that currently games will manage with the 2 gb for three screens. He settings you'd require to max the vram will mean you run out of gpu grunt first, and woukd need tri-sli. I think that's for bf3 though. Iirc there's a few guys here running 3 monitors on 2gb 680s that might chime in here.

Correct. With two decently clocked 680's (below) I run out of GPU power before I can even get close to applying the settings which would cause me to run out of VRAM. By running out of GPU power, I mean FPS drops into the 20's.

I wouldn't waste your money - unless you're going to go tri-SLI - getting a 4GB card. Otherwise the extra 2GB will never be able to be utilised due to the above mentioned point.
 
Yeah sorry, I wasn't saying get a 680, I was saying that there's no point getting a 4GB 670. A 2GB one is sufficient. A 670 can be overclocked to within less than 5% of an overclocked 680 (often closer).

If your going to game over 3 monitors i would go for more vram on the cards.

I think you are reading that wrong - they are not testing 4GB cards, they are testing 2GB cards in SLI and reporting the TOTAL VRAM across all cards (which is not how SLI works), so the near double of frame rate is from the extra GPU, not from VRAM

at the OP, as mentioned, 2GB cards will be fine for SLI, no point in 4GB unless you plan tri-SLI or greater

be aware that the 2GB 670 that you've linked to won't be able to fit the 670 block that you say you've already bought - you need short PCB 670's
I personally would go for the EVGA standard one - I have a normal one and a SuperClocked and they both OC to the same amount on air (but get noisy) so should be good candidates for OC'ing on water

as the 670 has memory on both sides of the card you might also want some small ramsinks for the back (if clearance allows)

Lol, didn't see this.

Thanks

Am I know right in thinking I cannot use a gtx 670 Ftw with waterblocks?

I would need a

I'm a bit worried about OC a gpu, I'm going to have a go with the CPU.

Also I want 3D vision, will this matter on the VRAM?

Thanks in advance guys

haha, I must have posted while you were writing this

yes, get that one :D
the FTW won't work with 670 blocks as it is a 680PCB with a 670 chip on it

from everything I've seen 3d vision doesn't affect VRAM useage, it's just slightly harder on the GPU
 
I'm half tempted to return my 670 waterblocks and go with 680's. Would you recommend or will 670 do me fine? (I'm a nightmare I know) :-/
 
670 will do you fine. No real reason to buy a 680 any more. I bought mine on 680 release day when 670 weren't even being rumoured so the choice wasn't there then.
 
670 is a shade off 680 performance for less money. It's something like 95% of the performance for 75% of the price, you could argue.

I'd go with an evga model if you're installing a waterblock, their warranty will cover you if you remove the cooler. Some other brands will maybe offer a 'don't ask, don't tell' kinda thing (msi, gigabyte.. maybe asus? idk) But the budget brands like gainward/palit, pny etc generally stick 'warranty void if removed' stickers over screws and stuff.

And yeah, 1000w is overkill lol. You can run 670 SLI on a good 650w psu (I'd go corsair ax 650 max budget, or xfx xxx edition lower budget.). You could've gone 850w absolute max imo.

Edit: at if FTW is better: it *may* overclock higher, owing to the extra gizmos on the 680 pcb, but for the most part kepler overclocking is 100% pot luck. Silicone lottery it's called.

the cheaper cards tend to OC to within such a close percentage of even the luckiest expensive one that I wouldn't worry about it, you'll be extremely unlucky to get less than 1200 out of any 670 on water, and very lucky to get more than 1300, 95% of all 670's hit somewhere between 1200 and 1300, so unless that extra 1FPS really bothers you, you may as well save the money (and keep the waterblocks you already have)
 
Thank you everyone for the great advice. Getting 2gb will save me £200. Can the backplates be installed after I set up the watercooling loop without draining it etc? I'm struggling to find any backplates in stock anywhere. Can see the evga backplates on the evga website, that's about it.
