dual core is not dual cpu, so if you have a 2.2ghz dual core system, you do not get 4.4ghz of performance (although you should, cheapskate intel!) the pentium d 2.2 gets about 3.6ghz or so of performance.
Well, my pc will pwn it!

with a 4ghz equivalent (amd64 3500+ venice core oc\'ed to 3.0ghz) squeeze those mhz! ya!

2gig of pc3200, dual 160gb hdd\'s, but the grapcics card lacks compared to yours, only a 6600 oc\'ed as i can\'t afford a 7800 (well, I *might* wrangle one, but probably not)
so actually, yours is really better, but...
