CPU Intel Q9450 Good choice Mobo Gigabyte P35-DS3R (I've had it in my last rig, rock-solid mobo...) I personally go with ASUS, but go with what you know! RAM 4 x 2GB DDR2 / 1066MHz (not sure about the manufacturer, probably will be going for either Mushkin or Patriot) Manufacture wise, Id go for OCZ personally. HDD 4 x 250GB WD SATA2 / 16MB (neede for RAID10) WD drives, perfect PCI-E nVIDIA 9800 GTX (most likely from BFG) You MAY want to wait for the 9900 card thats comming out, dunno when, but seen nformation online about them. I'd go with XFX or EVGA. I've tried all BFG, XFX adn EVGA cards, BFG being number 3 in the ranks for me. DVD-RW probably ASUS (or any other, I don't burn a lot of media) Not NEC or Pioneer? PSU Spire 650W active PFC Go for a 750W, more juice for anything you do in the future. Anyway, some may nto agree, but hey, thats my 2 cents.
