A 500W PSU like the ModXStream 500W will run it fine.

Yes, but, get 1600MHz RAM. 1866MHZ is a waste if you're just gaming.
Not a very power intensive system. 600W will run it just fine, but get 650W to give some headroom.

Thanks , but does RAM speed effect gaming whatsoever?

Nope. It'll gain you about 1/2 a frame in some instances, and that's the maximum effect it will have. 1600MHz or even 1333MHz (I'd go with 1600, though) will suffice for gaming.

If 1866 just costs a couple of dollars over 1600 there's no harm in getting it, but don't pay any real premium for it.

You might want to get a Cooler Master Hyper 212 Evo instead of the Hyper 212 Plus; the Evo is simply an updated version with better heat pipe layout and an improved fan (ostensibly).

650W is for two 7870s. One will run on 500W just fine.

Are you talking about only powering the video card or the whole system?

Sadly tigerdirect.ca doesnt sell them. Is the Evo worth it though? I will be overclocking to 4Ghz, maybe 4.5.

Well the Hyper 212 Plus is still good, the Evo is just that little bit better.

I just order from Newegg since they are both near the 35-40 dollars range

The whole system. A graphics card won't be using that much power ever.
