Home gamer, wireless + future upgrades

APPROXIMATE PURCHASE DATE: over the next couple of months

BUDGET RANGE: ~$300 per month until it's done (strange budget range I know)

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: games, creating home movies, adobe CS4, blu-ray movies

PARTS NOT REQUIRED: G11 keyboard, Habu mouse, SOYO 24" DVI, DVD/R, OCZ Vertex 60G HD, WD Caviar 500G, ATX Case, Fans, Win7 64bit, PCI wifi, 7.1 speakers

PREFERRED WEBSITE(S) FOR PARTS: Newegg & Microcenter local

PARTS PREFERENCES: only reputable mfg's. Prefer Intel CPU

OVERCLOCKING: Yes definitely

SLI OR CROSSFIRE: Yes, this is the future upgrade part. I will probably have to start with a single card then upgrade later as funds become available.

MONITOR RESOLUTION: 1920x1200 via DVI (future hdmi?)

ADDITIONAL COMMENTS: I do not have my home network wired so I will need room, preferably internal for a wireless card. I'd imagine this will become more problematic after the 2nd vid card is added.

I would like to get this project up and running with just MB, ram & vid card. Later I will upgrade to crossfire or sli, new (larger case), water cooling (maybe?), larger monitor & bling.
