Building My First Computer

So, around a month ago I made a post in this forum (which can be found here,) asking for some help creating a build for a computer I was planning on building. I was told that my original plan to buy parts as I gained more money probably wasn't the best way to go, I decided to wait until I had reached my budget to ask again, so any help will be greatly appreciated in helping to create a build!

Approximate Purchase Date: Tomorrow (2-18-2011)

Budget Range: $1450-$1550

System Usage from Most to Least Important: Gaming, Video (Video Editing), Internet

Parts Not Required: Keyboard, Mouse, Speakers

Preferred Website(s) for Parts: newegg.com

Country: United States

Parts Preferences: No true preference, though I was given a suggestion for a case that I think I'm going to use - Cooler Master Storm Scout

Overclocking: Yes

SLI or Crossfire: This is one thing I still don't fully grasp, if anyone would be willing to offer a basic explanation, that would be amazing.

Monitor Resolution: Not 100% sure, I'll need to look at my monitor that I already have.

Additional Comments: One thing that I am certain I want to do is the SSD HDD paired memory system, the SSD holding my OS and the majority of my games, and the HDD acting as a memory module for everything else I have. The case I linked is the one I'd ideally use, considering the fair price and the fact that I very much like how it looks. I definitely want to overclock at some point, so preparation for that now would be ideal.

Any help at all is greatly appreciated, and thank you for any time given!
