Any suggestions? I'm really trying to stick to a $1,000 limit

I'm not really sure about the motherboard or powersupply

And I'm not sure about the graphics card since it is a pretty small case I'm worried about heat. I will mainly use it for games like Battlefield 3, Crysis, Bioshock which is the reason I picked the 7950 over a 660ti since it came with Crysis and Bioshock for free. This is my first post so I'm open to suggestions. kthx

you can change back to the 7950 if you really want those games i would if the 670 is great to have in this price point

With the 7950 its simply a better option it's more than powerful enough to run every game on max setting 1080p 60fps, plus you get more than just bioshock and crysis, you also get tomb raider (everyone forgets about that one for some reason D.

Also in the end your pc is perfect you really do not need anything better than that.
