Personally i think the XfX has the better resale due to the double lifetime warranty, but some people like the eVga stepup, which turns out wont do me any good because the gt is cheaper than my gts was.
So it sounds like they are both good companies with good cards. I do not plan on stepping up, this will be my last video card pruchase for a while lol so I think i will go with XFX maybe or eVGa if its cheaper.
