I need opinions on the following builds.

I am planning on building a gaming computer and I was wondering which of these would probably give the best performance.

Only one is an intel rig. The rest are AMD. I already have a hard drive and optical drive. Some questions I would like answered aswell if anyone knows:
Which should I put more money into for a gaming pc, GPU or CPU?
Would AMD's A-series be good for gaming (APU vs. GPU+CPU)
What are the advantages of ATX or microATX?

Thanks.

Poll should say gaming* not building.

Sorry.

all of them are bad

I can only spend 600 dollars. If you do not have anything helpful to say, I suggest you get out.

Thanks, I like it alot. I take from the fact that the GPU is nearly twice the price of the CPU that, in your opinion, the GPU is more important. I don't need the hard drive, so where would I put that extra money to acheive best performance?

well an Os isnt included in that build.

for 20$ more you can get a better version of the hd 7950, cooling solution is better-> higher overclock , noise is less.

the i3 is no bad at all but it only has 2 cores.
the newer and also recent games tend to benefit from more cores.

fx 6300 would be the better choice.

Could I get you to rate this modified version of yours, I had to cut back on the gpu and the ram to keep it around 600 dollars. I'm not sure I will do the mail in rebates. http://pcpartpicker.com/p/1GsnZ
