Gameplay is smoother with no "microstutter" issues, especially in games with long draw distances where distant low res textures are swapped for better high res textures as you get closer to objects. (ie: Fallout 3 , Far Cy 2 , Crysis warhead etc..etc..)
Hey MTDEW, can you be a little more specific about the texture swapping? Why would one card do better than two in texture swapping?
I guess i wasnt completely clear on that point that its going from a 512mb card to a card with more memory that handles the texture swapping smoother.
And combine less texture swapping with no microstutter and the gameplay is way smoother.
I have 3 pcs running here at home.
When her 8800gtx 768mb / e6600 pc was playing fallout 3 smoother than my 2x8800GTS 512mb / q6600 pc, i knew something was up.
My pc benched circles around hers, yet in actual gameplay , hers was smoother.
Mine would just hesitate more when distant textures "popped" in.
So i removed one of my sli cards. (as suggested on here),
And my gameplay actually did get smoother with just one card. (i was surprised of course)
But hers was still smoother even though her, avg fps were lower.
Obviously, the sli was causing some of the hitching and having less texture memory was causing some also.
And the two combined made the game A LOT less smooth.
You can lookup sli/microstutter for a better explaination then i'll ever give, i actually asked on here about it and got a good enough explaination that its a necessary evil with multi GPU setups. (i'll see if i can find the thread and link to it)
And im sure theres no explaination needed why having more texture memory on a card in games with long draw distances helps since that part is obvious.
Anyway, i moved to a GTX 280 and ditched the SLI'ed 8800GT's and as i said, i couldnt be happier.
It really truely does give a much smoother gaming experience.
So in this particular situation , to answer the OP's question.
I say, get the GTX 280 and dont bother wasting time SLI'ing with another 512mb 8800GTS, he'll get better/smoother gameplay with the GTX 280. (or even the GTX260 / 4870 1gb)
