I already have 2xhd 5850 working cfx should i buy gtx 580 or gtx 590 or should i consider to use 3 way or even 4 way 5850 ? Because if i have to sell my amd i will loss about 50% my money before. If i buy another 5850 there is an option from saphire that only price around $140. I curently use Maximus IV Ex, Corsair Hx 850, 8gb corsair vengeance 1866(oc) cas 8-9-8, i5 2500k and two monitor setup. Please help i realy confuse here because that the curent king gtx 580 always call me to buy it 😛! I have no problem about the performance of my gpu but I just want my vga is in the top chart again. Thanks sincerely.
