No GPU because CPU has it built in.

If you can tell me what is the best for gaming, and what will be best for later upgrades I would love to see your opinion, or if you have a better build in mind that would be great also, my budget is $450 for desktop then the rest goes to monitor mouse and keyboard and such.

Build 1 i think

Are you looking to spend 450$ on those 3 pieces or on your whole computer.

And if your going to be gaming your going to want a good GPU no matter what.
So build 3 is a no go.

I would say the first build is the best for gaming in general, do you have a case, hard drive, optical drive, or RAM picked out yet?

Oh and is operating system in your 450$ budget or do you already have an OS
