[quote]If you can have a faster GPU and a total of 2.4gb VRAM, go for that. It's enough.
Note this 2.4gb of VRAM is not total VRAM, it is the max of 1 card, in the op's case 1.2gb of VRAM is the max.
The data in the VRAM is mirrored to addtional cards, it is not combined to create a larger total VRAM storage.
As such I personally would be more inclided to go with 560 with 2gb over the 570 with 1.2gb, and just look at OC'ing the 560's a bit.
hahaa... funny... this is exactly the two side of the arguments going on in my head for the last couple days... seems like there is no definite answer to this debate... it maybe easier to justify the 570 1.2GB if it is for a single monitor setup... thing just get so much more complicated once it is a 3 monitors setup...
but then again, I never see my cards use more than 1.3 GB.. usually below 1GB... so is 2GB a bit overkill? dont get me wrong, i definitely agree more the better for VRAM... but then now we also have the GPU power in consideration here....
