So I currently have an AMD A8 5500 apu with a xfx readeon hd 6770. I am looking to buy an upgraded graphics card so I can play newer games at a high level (ultra would be nice, but not necessary), currently I'm in Crysis 3, Tomb raider, and bioshock infinite and just want to see them at their potential (crysis 3 especially) I just had a evga 660 sc and it worked well for me, I just got it at best buy, realized I got ripped off price wise, and returned it to get a better deal online. now after more research I am trying to decide between a radeon hd 7870/7950 or gtx 660/660 ti. (but open to suggestions looking to spend no more than $350) I am worried about the A8 bottlenecking the gpu, but will that be an issue?
