I need help! I just built a new computer system and I’m experiencing very poor VGA performance. When I run the Batman: AA benchmark @ 1900x1200 with visual and physics settings maxed out, I only get an average of 19 FPS. On my old LGA 775 motherboard with the same video cards I would average around 75 FPS. Every game I run looks like a slide show because my frame rates are so darn low. My specs are as follows. Motherboard: ASUS Rampage II Extreme LGA 1366 Intel X58 Memory: CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 Power Supply: CORSAIR CMPSU-1000HX 1000W ATX12V 2.2 / EPS12V 2.91 Hard Drive: Western Digital VelociRaptor WD3000HLFS 300GB 10000 RPM 16MB CPU: Intel Core i7-920 Bloomfield 2.66GHz Graphics: 2x BFG NVIDIA Geforce GTX 260 OCX MAXCORE 55 896MB SLI Physics: EVGA Geforce 280 OS: Win 7 and Win Vista I have updated all the motherboard drivers from the Asus website, I’ve tried both win 7 and win vista; I’ve updated my video card drivers. The problem exists when I run the CPU at default and over-clocked speeds. My video cards worked flawlessly in my old system. I’m beginning to suspect I have either a bad motherboard or power supply. When I have more time this weekend I will try my old power supply in order to narrow the problem to the motherboard. I consider myself somewhat knowledgeable when it comes to building and trouble shooting computers, but I’m stumped concerning this issue. If anyone could offer any help or suggestions that would be great!
