Hey guys,
I've been doing some research into my setup recently and am considering swapping out my 6990 & 6970 trifire for 2x 7970s in crossfire.
Before I do this I have a could of questions.
1.) Do you think this would provide improved results compared to my current setup? I've found some rough benchmarks of 6990 vs 2x 7970 but nothing mirroring my graphic card setup. The 7970 is meant to have better scaling... plus I know that trifire doesn't scale massively well.
2.) I currently have a 1156 chipset motherboard. I know that running two cards may limit the speed that these can run... e.g. The PCIe speed will not be 16x on one card & 16x on the other. From what I've found so far though this doesn't hold back the cards too much if at all... Will the 7970 be crippled by using them on this board though? My board is a P7P55de-Pro. It supports PCIe 2.0 but obviously not 3.0. I have read that in single card usage this made no difference to the 7970 but I was wondering if it would in crossfire?

MB = Asus P7P55D-e Pro Chip = 1156 i7 870 Oc'd 4.09ghz, [B
MEM = 16gb DDR3 Ripjaw @ 1600mhz GPU = VTX3D 6990 + 6970 Tri Fire Monitors = 3x Dell SP2309w @ 6256 x 1152
