After doing more research most say get the basic i7 chip and best single video card. Faster RAM is nice, but anything over 6gig in 3x2gig tri channel is over kill. Also having OS and software on one hard drive and data on another is a must too. I will probably build something like this soon.
Intel 920 i7
6 Gb RAM
windows 7 professional
Intel 80Gb SSD for os and software
1Gb Samsung F3 drive for data
blue ray ROM
24x dvd burner
Radeon 5870 Video Card
back and forth on motherboard whether to get one that has usb 3.0 or not.
Thinking about it RAM is relatively cheap so bump up to 9 Gb would be fine.

I would be EXTREMELY wary of buying a system from ibuypower or cyberpowerpc. Do a google search.. heck, even search the cyperpowerpc online forum and you will see what I am talking about. There is a reason they are cheaper than other places.

Just keep in mind that if you have a problem with your new system, you get the joy of boxing the system back up, praying you can get ahold of someone to get a RMA number, paying to ship the defective system back to the company, waiting to see if the system can be fixed, and then waiting for the system to be shipped back to you... all the while sweating the 30 day money back deadline that starts the day the system arrives at your house.
Some people have had great experiences with these companies, but just be sure you realize the potential trade-off you are making (cheaper price vs. shady customer service) before you click the "purchase" button.
Just my two cents...
