So I recently came into an extra $100, and am not sure what to change about my build. Ideas?

but due to money i found in the couch cushions, i now have $830, instead of $730.

Should get a better graphics card? Motherboard? do i even need higher than a 4 core processor?

The FX 4-Core doesn't just have less cores-- it's also slower. The 6300 is a great processor, stick with it. If anything, I'd spend the extra $100 dollars on the GPU, and consequently the PSU.
