will I be able to max out crysis 3?

Solution
I ran the intro levels on max settings at 45-60+ FPS on a Phenom II 1090T @ 4.0GHz with 2 Radeon HD 7950's in crossfire @ 1000/1400.

All 6 CPU cores were around 80-90%
Both video cards were at 90-99%

Your 8120, even though is is Bulldozer, is an 8 core and Crysis will benefit from that. I'm thinking a single GPU will be the limiting factor, but it is still a very good GPU.

My suggestion is to try the benchmark mentioned earlier at different settings and see how your system does before you make any changes.
