Yo Garcian, check out the Canadian Newegg not the U.S. one, hes from there. I made the same mistake too, so its NP to do that. Though, surely it would be better to pick up a 58xx series, especially as the compute shader is relevant to modeling and encoding? Also the price difference is v.small.

Thats also a pretty good one as well.
Tease.
