I'll be buying soon and wanted to know if there are any improvements that could be made for my $650 gaming PC.

That's a well balanced build, not too expensive, but will perform well enough. The only thing i'd point out is that there is a 7950 for the same price (after rebate and on-page promo code) that is much more powerful than your 660:

Good luck!
