So I'm building a basic low/mid range PC for basically an all-in-one entertainment system (Xbox replacement), and I'm struggling to decide on a GPU. This is a HTPC build running a i3 4170 (for now).

As much as I love the 750ti's power consumption, the 2xx series are just a way better value. So it's down to the Sapphire Radeon R9 280 (3gb) which is on sale now for $160 and the Asus 270x at $165. Right off the bat the 280 seems like the better deal, but I want to get some second opinions first.... Anything I'm missing?
 
Well lucky for me, this build still requires a PSU. I was thinking Corsair CX600M/CX500M.

Annnnndd as I'm typing this I see the million other threads regarding the same question... Sorry guys, next time I'll search first :)
