Time for a new PC

[Naysayer]

OK I am currently on my Mac it is old, Dual G5 2.5 GB ram. Runs up to 3 WoWs ok. Never been super but never really sucked either. It is time for an upgrade though. The new Mac Pros are 3 grand. They rock but I can build something much cheaper that is close enough in performance. My goal is under $1000 (us).

This is my starting point

I have a Fry's close by as well. It has been a few years since I have done this and, after going through New Egg, I am behind the times. Are there any suggestions or comments on what I have going in my list? I have no clue on things like cases and the last power supply I bought was like 400W and very close to cutting edge.

Goal is to 5 box on 1 computer. Probably going to go to 64 bit Vista (shudder)
Thanks for looking.
I have two HDDs already that I just remembered I will raid 0 them in my new box. 7200RPM Seagates@ 350GB, more then enough.

Nice, very similar to what I upgraded to.

q6600 2.4
4gig ddr2 1066
Asus EAH4850 x2 crossfired (1 was enough, but i went 2 since the price was right with a newegg $30 rebate x2 and my mobo supports pcie 2.0 16x2)
Gigabyte x48-ds4 mobo
Vista64bit Service pack 1
22" acer widescreen monitor (FREEKING HUGE)

I run manually capped at 60 fps on the main and 40 fps on the slaves set by maximizer and have no issues whatsoever. The game has never looked so pretty.

This is a great card and the price is amazing.
