I decided to build a new PC - ordered these parts: Intel Core i7 920 D0 2.66GHz Socket 1366 8MB Cache Retail Boxed Processor MSI X58 PRO iX58 Socket 1366 8 channel audio ATX Motherboard XFX HD 4890 XXX Edition 1GB DDR5 Dual DVI HDTV Out PCI-E Graphics Card Corsair 6GB (3x2GB) DDR3 1600MHz XMS3 Dominator Memory CL8 2x Western Digital 1TB Hard Drive SATA300 7200rpm 32MB Cache Caviar Black Coolermaster Centurion 590 Coolermaster Real Power 520w Modular 2x BenQ G2410HD 24" TFT Monitor 1920x1080 300cd/m2 40000:1 (dynamic) 2ms 16:9 DVI-D/VGA Glossy Black Saitek Slimline Aluminium Effect Keyboard Microsoft Wireless Laser Mouse 5000 Anything else you think i'll need? better heatsink / fan? - I never bother OC, so whats a good HS/F that isn’t to expensive just to improve things. Also would a 10,000rpm drive improve performance much? Or is it hardly noticeably to bother. Last thing: If i was to put a second 4890 in it – would i need to get a PSU with higher wattage? Or is my PSU fine for it. Plus would i see much performance increase with a 2nd one in there.
