mine for 1300$ and 200 of that was windowsXP. Need to add 100$ toh, for a decent powerssupply. this one came with the case. I have read on the abit forums of people overclocking the p4 2.4@3.5 routinely. This would require some prescription cooling, but after i get a new PS I will try for 3.0.
My system at 1280x1040 blows 45-70 fps in AH2, my refresh is 70, so that is very playable. No overclocking yet. hardly any tweaking of the stock featurs, just waiting on a decent PS so I dont junk my sht.
