Which GPU do I really need?

Urlier, some nice guys confermed that the XFX 7870 Double D is a nice card.


But I decided that I might do a little (very little) video editing on it. Is premeir or a program like that require a 7970? Or with the 7870 be enough for someone like me who wants to build the cheapest but good quality editing/gaming rig? I'd like to stick with the 7870 if I can.


adobe premier uses cuda if i am not mistaken... nvidia might be an option  but if you are mostly gaming then you might get better value with amd
