So you are my favorite person right now.
So heres the dealeo...
I already have a system, specs below. And I want to keep my 9400Gt without buying another card, and If I did buy another card, Id make it some high end super card, like 2 4870x2 in crossfire, and if those 2 got lonely, then I always have another PCI-E slot to cheer the cards up.
(What could you do with 4 Gigs of VRAM?)

Specifications...
Mobo: ECS GeForce 7050M-M (Plan on upgrading)
CPU: Phenom Mark-I (Maybe get a Mark-II in the future)
RAM: Corsair something something, Linx
HDD: WD 2x 300Gb in RAID 1 SATA, 300Gb IDE (Is SATA or IDE better for OSx86?)
GPU: BFG 9400Gt 512Mb
Wifi Card: Linksys WMP54G 4.1 (Is this compatible?)

If you could tell me if I need to fix anything I will do anything you want. Including giving you a shoutout in my YouTube videos.

EDIT:
RAM Link was the wrong RAM, link updated.
