This would be amazing, I have been thinking of replacing my r7770 and giving to my friend for his pc that i am building him and this would be a amazing replacement for it.
I usually buy XFX for video cards and PSUs as they've never let me down. In the two times I've had an issue (over 10 years) they're warranty service has been excellent. A 7950 would be damned decent!
This would definitely be a really nice upgrade to the 5770 I'm currently using. Having little to no disposable income is not the most fun thing around.
