Please dont think that SP1 did much for us dual core guys. You single core users get much the same performance as we do. The second core may get used but who knows what it is actually doing, maybe counting sheep as it does very little to improve the game. I can disable one core and there is no change in scenery draw or fps ie no difference if i have them both running or not and it seems intel guys have same thing. Although it is nice for the non pc wise guy to look at the charts and say ,oh dosnt that look pretty. Oh yes i get same problem.AMD X2 64 60002 gig ddr2 800 MHZ cas 4 ramAsus M2n moboNvidida 8800GTS 320 meg video ( should of got the 640 )2 X 250 gig SATA hd
