Mid level gaming Comp - Barebones Kit

Hello all,

I'm currently using a Dell 8400 from 2005. Specs are: 3.0 ghz P4 with H.T., 2 gigs DDR ram, GeForce 6800 256mb video.

I've been toying with the idea of building a machine for some moderate gaming because my Dell is showing its age. (I like to play Company of Heroes, Rise of Nations, the Civilization Series, Command and Conquer Series, Call of Duty, Battlefield Series, etc). I typically play on 1024x768 video resolution (I find that to be the most comfortable for me). I also use Office 2007 a lot.

I saw this bare bones kit from Tiger for only $399 and I wanted to get your all's thoughts on it. I like the price. Please compare this bare bones system to what I currently have for mid level gaming and Office work.

Kit specs: AMD Phenom 9500 2.2 ghz, 8 gigs of OCZ Blade PC 6400 800 mhz ddr2 ram, EVGA GeForce 9400 GT 1 gig video, MSI k9n2 SLI MOBO, 550 watt PSU.

Here's the link:

So, how would that bare bone system compare to what I already have? How about the next 3-4 years (games/applications)? I would also get another 9400 GT and SLI them. Would that improve video performance?

THANK YOU!
Mike

weak processor, overkill on the RAM, weak graphic card...very weak
