Shame i didn't notice this post sooner
i'm a dab hand at building rigs! The one i'm using now cost me £600 which is sadly $1,190 USD
has
200gig HD space
7900GS 256MB PCI-X
Abit AW9D-MAX (motherboard Rocks!)
2.8gig Pentium D 800FSB
1gig DDR2 667mhz RAM
570W PCI-X Power Supply and make sure it s a 24pin for PCI-X Mboards not 22!
iCute Case and other assorted Gubbins!
atm i'm running 2142 on High Detail but in high pop servers i knock it down the Medium and it runs lovely!
but if you can get the 8800 gts which here the pop for here around £200 in USD thats around $396.92 get it as they run like buggery!
as for OS i wouldn't touch Vista with a 40ft shit stick! stck to XP Pro at least it's compatable and stable providing it's configered right!
The Above cost me £600 Flat from a Computer Fair which is something i would advise looking up! theres always a one about but remember to get proof of purchase and the number of the dealer that sold you the Hardware
