5770 crossfire on 8x/8x worth it to upgrade my GTX 260? Tags: Radeon Gtx Crossfire Graphics Last response: April 16, 2010 1:51 AM in Graphics & Displays Share tuesday0180 April 15, 2010 11:45:42 PM I currently have Phenom II X4 955be 2x2gskill 1333mhz ddr3 ram GTX 260 core 216 Gigabyte 890GPA motherboard with 2 pci-e slots. I believe one of the slots is full 16x and if I put a second card in it splits it 8x/8x Would it be a worthwhile upgrade for me to get two 5770 crossfired? Also, I have a thermaltake 600watt purepower psu. Would I need a new psu?
