I'm still looking for a new GPU after my last one died. I was looking at the R9 270x, but I stumbled across forum posts about the R9 270x basically being an OC'ed R9 270 that was rebranded. Is that true? I'd much rather buy a 270 and OC it than buy a 270x for $40 more. Benchmarks show an OC'ed 270 to 1.1GHz beats a stock 270x.
