Hey guys a friend of mine bought a Dell and it came with a 7800GTX 256mb in it. He told me it was made by dell and not another company like XFX, eVGA, Leadteck, etc. I plan on buying it from him but i'm not sure if it will work in my non-dell comp. Does dell actually make graphics cards? and will one work on my comp? Any info on the subject would be appreciated. Thanks.
