Re: Advice on making my build better
You should keep your questions in one thread, because theres so many threads posted about you. But I'll reply anyway.
For the PSU, the Corsair 620w, will handle that fine.
For the hard drives, you can raid 0, two Seagate 7200.10 320gb hard drives. Or do what salty, suggested about raiding all those 500gb for security and a performance boost.
You don't need the extreme edition. For much less, you can get the Q6600, which is only 200MHz slower, and just overclock it.
That will save you some money right there.
