Decent $600 gaming-rig

Hello guys! I know $600 may not be much for a gaming PC but can someone point me to the right parts?

Thank you so much and I appreciate any help!

Does that $600 include OS/peripherals/monitor?
How big a harddrive?

Probably a 500GB HDD And no OS (has own copy), what do you mean by peripherals? And if there's some extra, a monitor could be useful

Mouse, keyboard...probably no extra for a monitor. A large monitor alone could cost half your budget.

That leaves you a bit of room for a case, and whatever else.

Whoa that was quick! Let me check them out Thank you so much for the help! Please do still visit this thread 'cause I might have some more questions if you don't mind

I wouldn't bother reading newegg reviews.

Oh, thanks for that tip.

For the casing, what would the Mobo fit into?

Basically anything thats not absurdly small...it's ATX standard sized.
It should fit into anything here; I also included a no powersupply requirement in that list since built in powersupplies aren't always the best.

A cheap case that I'd recommend (I actually have one) is the Antec Three Hundred Black Steel ATX Mid Tower Computer Case. It's a little bigger than an average store-bought computer.

If you're already using it, then I'll probably go for it too. For the PSU and optical drive, I'll probably salvage from my previous PC.

Optical drive, sure.
Power supply, probably not.
Specs on your old powersupply, including 12v rail amperage?
Or a link/name is fine too.

Dynex DX-400WPS

What do you think?

Ahh, nope.

Phew Thanks for saving my butt

No problem.
EDIT: Nevermind.

I've placed the order. I hope everything goes well! Thanks a bunch!

Nevermind?

EDIT 1: And oh, by the way, for the GPU, it says it needs a 450W PSU?

EDIT 2: Oh nvm, I just used the PSU Calculator http://www.antec.outervision.com/PSUEngine and I guess that'll be sufficient enough with a bit of overclocking.
