Headline says it all I've been rocking my 690 for about 2 years and it seems to be almost impossible to find a site that would compare 980's in sli to a 690. I know its older and the more vram would be better. But would it be better to hold off for a 990 which seems likely with the low tdp on these or just pick up 2 now? Any thoughts folks (rest of the system is fine cpu will not be a bottleneck).
