Generaly graphics card is more important in gaming then cpu, thus go with amd cpu and get better graphics. Though I would say, that fx 6300 is better price/performance choice then fx 6350. Also, if you can get it, get rather r9 280x then gtx 770, you might save some money (unless youre in US) for very similar performance. Also with the saved money you can maybe pull off an fx 8320, which would be much more future proof then 6300
