That FX 4170 won't bottleneck the Radeon 7850, though an i5 would increase frame rate some.
That's what I thought when I bought it, it's not the best but it it's a decent entry/mid level. What sort of settings do you recommend I play on? I can get 60 out of it on ultra 1080p with some severe spikes in places on fallout 3. What is a good place to start with settings?
