Best GPU for $150-175?

I'm looking for a good card in this price range and currently considering the R9 270 but have also been looking into the 750ti. Any suggestions?

270 > 750ti. What psu do you have ?

R9 270 .

But second hand 7950's or 670's are a good price / perf .

My Asus 7970's that have about 80 hours of game play with box and papers.

You can get R9 280s right now brand new for that price.
