$700 new system build

I haven't built a computer since 2004 and now I am in need of a new computer cause my last one completely gave out on me. I'v been reading a lot expecially on tomsguide.com and have been able to pick up a lot of valuable info. But just so I don't make any mistakes, I thought I would see what you guys think.
I just need some opinions or suggestions.
I don't need anything else except for these unless you guys think I might need something else.

Hard Drive http://www.zipzoomfly.com/jsp/Prod [...] e=10007194

The memory I'm not sure on since it had no reviews on Newegg.

The Motherboard. It has 1 PCI-E 2.0 x16 slot 1
PCI-E x8 slot and if I were to crossfire it would it run at x16 or x8?

Oh and by the way i know that newegg is out of stock on the video card. But i'm sure I can find elsewhere.

Oh yeah i'm missing a cd/dvd burner what do you guys suggest for that.

Thanks!

Do you need an o/s (Windows) included in your budget, and what is the intended use of your pc...gaming, surfing the internet, etc....

To answer your question...two cards in that mobo would have them running at 8x and 8x

I'm not sure what the warranty specs are on that card. As far as the bandwith for a dual vid card set up in that build...no it will not affect it with your resolution. You will be just fine.
