I play at 2560x1600.

It seems my scaling is stuck at about 250% at best. Which really isn't that bad considering, but how much would I benefit from the extra VRAM and only having to scale 1 card? Is it worth it?

the v-ram would be the biggest benefit, and there is always the ability to add another 580 in the future, you may decrease a bit in fps though.

It's worth it to move to the dual 580's. Although yes the vRam will help, seeing the resolution you play on, two cards would probably be better. If you were going to Surround Vision, then yes three cards would be better than the 580's. But you can always add a 580 down the road if you added monitor real-estate

Thank you for your input, and wow, we have almost identical systems.

Do you have step up on those 570s?
post #7 of 27
It depends on the games you play.

If you ARE limited by the VRAM then a couple GTX580's would solve the problem and give you slightly better performance.

If you're NOT limited by the VRAM then moving to a couple GTX580's will be of no benefit at all.

There's an option on EVGA precision and MSI afterburner to monitor VRAM usage on the GTX500 series.

Best thing to do is play a couple of games with the VRAM monitor enabled and see if you really are running into VRAM limitations

At that resolution even if he is not limited a card with more VRAM will perform better.

Sell your gtx570s and get GTX580's in SLI with the 3gigs of memory. They are only like $60 more and you wont be bottlenecked in the future.

I fail to see how you work that out?

If a card is not VRAM limited then there's no performance loss, Adding more memory meens the card is still not VRAM limited so there's still no performance loss.

In order for a card with more VRAM to perform better the original card needs to VRAM limited.

If I play Counter strike at 2560x1600 with my 1Gb 5850 I'm not VRAM limited so playing the game with 2Gb of VRAM will provide no extra performance as there's no need for the extra VRAM.
