Broke and want to game but your current computer sucks? Build a machine with an A10-5700 (or 5800k but only if you're going to do overclocking, otherwise it's not worth it as the 5700 is identical but with locked multipliers). Unless they're the same price, then get the 5800k anyway.
Have a larger-than-$300 budget? I3 or I5 plus discrete graphics would suit you better.
