my cpu is the new "b" batch. here's my review. i currently have it on p5b deluxe mobo (my real mobo is p5b deluxe wifi but it died 20 mins into running for some apparent reason which was unbelievable). with ocz ddr2 800 mhz 4-4-4-15 ram, i am currently at 3.3 ghz with ram at 475 fsb and 5-5-5-5-15. i am probably ram limited. system is stable. no 3dmark benches since my gto wont arrive till monday. no final benches until my real p5b mobo arrives from RMA. pretty satisfied at the moment
