2 x 670 Advice

[sas30uk]

Hi guys im looking to get 2x 570s and have the following PSU http://www.overclockers.co.uk/showproduct.php?prodid=CA-096-CS&groupid=701&catid=123&subcat=1084

Would this be sufficient to run 2 x 670s on ?

Thanks in advance

Yes.

Yep. A very good PSU and plenty of power left for a good OC on GPU's/CPU

Thanks guys greatly appreciated

Wouldn't surprise me if you could run 3 on that

Complete waste of money if you are using them with the monitor in your sig. A single 670 will do but so would the single 580.

If you're going for multi monitor gaming don't get the 2Gb version (based on comments on this forum that 2Gb VRAM doesn't cut it when multi monitors are involved)

But surely 2 670's will total 4GB and do the job fine ? Please let me know soon as i will cancel one if what you say is right.

it's only worth getting 4GB cards if you are going to get 3 or 4 of them... with 2 cards you will run out of GPU power before VRAM, if you wanted 4GB cards then you are better off waiting for GK110 to come out next year and getting 2 of them

cards in SLI have to maintain an exact duplicate of what is on the main card, so 2GB + 2GB = 2GB effective

Nonsense. In fact the absolute opposite was said!

4GB only worth it for 3 GPU's and above on 670's/680's.

Nope the VRAM isn't cumulative. So 2GB effective.

Going by comments from this forum and me and Rusty that use 5760*1080, 2GB is enough. Please don't advise people to spend more than they should with out doing research. The 4GB cards only become effective when Tri/Quad SLI is being used.

No it doesn't work like that. It's still 2GB. But that should be fine for triple 1080 monitors.

I ran some benchs and here is the results.

I see people giving this wrong advice a lot!!

I'll be running 2 with 2gb soon. I don't expect to have any issues.

At the moment I'm experimenting with 3x 21'5 TFTs in 5760x1080 res on 3x GTX 670 2GB cards, and sofar in the games tested I haven't met a vram wall.
