Hi. I'm selling my my MSI P45 and want to get a Asus board in return. I can buy a Asus P5Q Pro for €119 or i can get a Asus Maximus Formula X38 FRG SA for €159. (I also bought second HD3870 on Ebay for €40 but the guy sold it as broken because he said the card was overheating and got black screens while gaming. Me thinks it's just bad contact with the cooler. It's the Club3D one and has 2 coolers. The stock one which is pretty decent and a Arctic Cooling Accelero S2) So i want to use Crossfire if i can get the card working. A few points: How good does the Maximus oc? (can it do 1600 FSB) Is it better for Crossfrire? Is there much difference between the X38 and P45 chipset? And last is it worth the extra cash? Please share your thoughts on the one. Thanks.
