Currently I have an FX-4100 at 4.3 with an HD 7770 playing at 1280x1024. My birthday is coming up and I am going to get a new monitor (most likely 1080p) and also a new GPU. Do you think that the GTX 760 (or any other GPU you can suggest for 1080p) would be fine with my FX-4100 at 4.3 or do I need to get an FX-6300 or 8320/50?
