your mit as well get a

processor :quad core q6600 2.4 fsb of 1066 to 1200

ram: runing ddr2 2gb ram at 1066mhz or 1200 or even 1600 supports up to 8gb of ddr2 ram

Motherboard asus P35 blitz extreme or

asus P5KC which runs ddr2 and ddr3 memory with fsb of 1333

6 sata serial ata2 3.0gb/s

with a good 512mb

or 768mb graphics card should be good for dirt

and 7200rpm seagate serial ata2 drive 320 gb runs at 1.5Gbs or 3gb/s

have at least two hard disk drives of equal speed as above

should be a sweet gamming machine

You will need at 2gb DDR 2 ram runing at 800mhz or even 1066mhz

if the motherboard you have can run at that

at least pci e graphics card DDR3 256mb 512mb ram at at least 128bit or even 256bit

I have dual core 3GHZ processor

with

2gb of kingston memmory runing at 800MHZ

256 DDR3 ATI radeon 9550 cpu speed 540MHZ

with two

Serial ata 2 drives 1 320GB and the other 120GB seagate barrcuda drives

which manually set virtual memory setting to 2046 to 4092 for both harddrives

makes the computer access time quick when using application and the games run at 32bit 1024 x 768

with need for speed cardon and need for speed most wanted at 32fps

so if you

can get your hands on a Asus geforce 8600GT DDR3 512MB 128bit core speed of 540MHZ PCI E Price should be between 180 to 280 dollars if your computer has this port

or Asus radeon hd 2600XT 256MB DDR4 128bit dvi HDMI PCI- Express core speed of 800mhz price should be between 190 to 300 dollars

or even two asus radeons connected to each other
