Everyone, I don't want to make a super-long multi-quote post, so here's what I basically have to do.

I have to go with the E4600. I know the trade with my friend may not seem like a good deal, but it's kind of a mutually beneficial thing. His parents will NEVER let him spend more money on a graphics card, and my parents don't give a sh*t, but I do need parts.

I kind of wish there was a way to make my build better and keep him happy. He did say he has an E6550 I could use instead, would that be any better?

P.S. I don't actually HAVE the GTZ260, I have to buy it and then he will trade me.

P.P.S. I don't really want to go AMD..... will be running OS X on this system quite a bit and it will be easier than Intel.

Thanks for all your help, everybody! (Assuming I get the E4600 or E6550, what can I change on my build? I am gonna order parts this afternoon. Some of them, anyway.)
