yeah and even then I don't think you would see 60 constant fps, it might dip into the 45-50's area still. How much of an overclock? the 280x is strong so that is good, an FX 6300, assuming truly stable, at 4.6 Ghz will match a stock 8320 performance, and that should get you 50-60 solid FPS...Maybe change some sort of blend of very high and ultra settings might be needed..
