Hi guys, my spec is as follows:
asus a8n sli deluxe
amd64 4000+ 2.4ghz
2gb ram
Geforce 7900GS 256mb
Windows XP

I thought this would be an alright spec pc to play this game and it would run 1280x1024 on high settings?
Maybe im wrong.. or am i just suffering the slowness you guys are?

Yeah dude, it should run good with those specs.
If you don't own the game and you haven't tested the settings yet, I reccomend going to http://www.systemrequirementslab.com/referrer/srtest This website reads your specifications and etermines how well you'll be able to run the game. You can also download the SCDA single player demo. Test different resolutions (I reccomend starting at full resolution and working your way down if you suffer from any lag, which is unlikely with your current setup).
