The question is, why should we buy from YOU? . Seriously though, OCN discount perhaps?
Personally, I'll buy whichever brand GPU is cheapest. I do avoid XFX and Gigabyte though. Any other brand is cool with me. I compare warranty and cooler design on the cards I'm looking at, check out prices. Whoever has the best between all 3 things I look for, that's what I grab. Again, AVOIDING XFX and Gigabyte.
