Cyber Monday I'll be ordering my build but I'm torn. Should i get a Pentium G860 (65$) and an HD 7770 and get an i5 sometime next year or get a Pentium G2120 for 88$ or and i3 2120 for (99$) and an hd 7750.
IMO, the first option will be better. However, in both the cases, it'll be your GPU which will bottleneck in games, rather than your CPU. Still, G860 + HD 7770 is a more balanced configuration.
The 7770 will be good enough for medium settings with the i5 but 7750 and i3 wont do in battlefield 3
Wait for the i5 and keep the G850 money for a better gpu
