Ie GX2 to 280.
If you buy a GX2 on fleabay and not from a reseller (which there are limited ones EVGA supports) then you not only will lose warranty but also the ability to step up as well.
My .02 I own a GX2 as well as an 8800 Ultra. I was getting stuttering with the GX2, installed the Ultra even though an older card, get better FPS and no stuttering..........I am happy for now.
Debating moving to a 260 as well.
