Hi, I have an Xpredator with 1x 200mm Top case fan ehaust, 2x 120mm coolmaster side case exhaust, 1x 120mm coolmaster rear exhaust and 1x 200mm front intake. MSI GD65 Z8Z i7 477k not over clocked XFX 750 gold Pro series PSU 16Gb @2133Mhz (2x8Gb) XFX HD 7990 I want to know, now drivers have stabilized and 99% of issues seam to be fixed with a single 7990, is it a good idea to ad another XFX HD 7990 with a 1250watt PSU into the mix for gaming? I've recently been offered the two and I intend to buy tomorrow! Any idea's or thoughts would be greatly appreciated. Thanks in advance.
