Normally, the GPU is the quickest way to gain gaming frame rate. But since you have a dual core APU, I'd say it's a toss up. You should go for a faster gfx card first followed by an A10-5800K or 6800K
I see well I'm considering a GTX 660, is that the best GPU I can grab for my 450Watt PSU?!
Also would it be a bad idea to just go ahead and upgrade my cpu first?
Well, if you stay with the dual core APU, it may bottle neck the card somewhat. If you plan on eventually upgrading the APU to one of the faster ones I mentioned, then the card will get to use all its 'horsepower'. In the meantime you will see better gaming even with your dual core.
As far as the PSU, yes... 450W is sufficient. But It will depend on which 450W PSU you have. Do you know the make/model?
