ah ok so what mobo you recommend and what kind of psu cause all i need is a video card and i was going to go 6800 ultra oc overclocking but you can make some suggestions
The same goes for mobos. Your case is a micro-tower, so buy a micro-ATX. There are many good ones out there, but remember this... you'll have to reinstall WIndows afterwards, as well as everything else that is on your hard drive.
Your motherboard will handle an AGP version of the 6800GT.
