Ok my build consists of the following which I will buy from ncix.com cause I live in Toronto. The build comes our to $1000 after price matching.
Cpu: i7 920
MB: Gigabyte x58 UD3R
Ram: OCZ XTC Gold OCZ3G1333LV3GK 3GB 3X1GB DDR3-1333
HD: Western Digital Caviar SE16 640GB
Video Card: HD 4850 or GTX260/4870 if I can get it on sale for ~$180
Case: Antec 300
PSU: A quality PSU i can pick up on sale
Now my biggest concern is the PSU....would a 500w from a good company like seasonic be able to run this rig without problem? Keep in mind I will not be overclocking and assume my video card will be a gtx260/4870. Also how is the ram? Is lower timings better?
