My GeForce 9800 GTX is finally slowly down a little too much for my tastes; it is having trouble driving games at 1920x1200.

I think I am going to get a 5870 in the near future, but I really don't know much about the card makers for the ATI chipsets. If I was going to go nVidia again I would go with EVGA no question. The only name I really know for the ATI cards is XFX.

Who would you guys suggest? Or could you point me to a Comp Builder Forum where I could get more info?
