2.2 ghz....
2.2 mhz wouldn't even...do...anything really...Might just take 200000000 years to boot up the computer lol.
I used to have a P4 on the same computer as you, 5-6 years old...my processor was 1.8 ghz...But I just upgraded to a 6600GT vieo card, and an Athlon 3200 @ 2 ghz...and it's probably 3 times as better...
My lfs frames went from 60 FPS at the lowest settings to 60 FPS with full settings, 4x AA and 8X AF, but I run it fine without ANY lag ever at 8x AA and 16X AF
