I have CF(7950 + 280) 1100MHz OC(7970 level of performance not the GHz version) for quite some time now, and I am happy with it, really good scaling, zero microstuttering, and no issues, however some games don't have CF profile doesn't support CF or SLI, so ruing at 2560x1440 with a single GPU is a big problem. So I am thinking to buy a single GTX970 with an custom cooler, OC to 1500MHz in order to slightly surpass the GTX980. From what I have see a GTX980 is around 10% slower than my GPU setup, and in the games that don't support multi GPUs the performance boost that I will gain will be massive, + 0.5GB more vram is a welcome addition. http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_980/26.html look 980 vs 7990 (7990 = 7970 CF) The cost is not even worth mentioning, because I will sell my old GPU's, so over all I will end up paying around 40 euros. What do you think guys should I do?
