OK, thanks guys. Right now it has integrated graphics, so I want to upgrade the video card. It's a new computer that I got yesterday. Specs:
Intel Core 2 Duo e6300
2GB PC4200 RAM
250GB SATA 300 Hard Drive
16x DVD(+/-)R/RW 12x RAM (+/-)R DL Lightscribe SATA drive (also CDR and CDRW compatible)
Integrated graphics shared with main RAM
Oh and after I install the X1600XT, will the integrated graphics still share my RAM?
