[Harley the rookie]

I don't know which gpu should i get.... the r9 270x sapphire or r9 280 sapphire (the differences in price is just around $20)

I'd get an R9 270 and OC it up to R9 270X levels.

280 all the way. 280 = 7950 plus overclock it and you get 280x 😉 have little insane power!.

Go big or go home. 280, not quite a 280x, but in the ball park and a big step up from the 270x. something like 1300 shader count to 1800, somewhere in there. Big difference when it gets down to the nitty gritty.
