Impressive Alpha-Pre Performance with UAD-2

Hey Billy, my system is similar to yours. I just got a new Asus P5Q E mobo, for my Q6600, and I have a delta 1010 PCI w UAD-1. Of course I use the UAD options in Reaper with the proper stuff turned off, but I can't play a session at say 256 crackle free if I'm using say (40% CPU). Could you share you're services that you have off, and what could get me in that 64 ms crackle free world? Also, I have 3 7200 RPM SATA II drives connected directly to the board, 1 for OS, 2 for crap. Thanks. Need the help, oh I do use internet on the DAW, XP 32 SP3 Pro. Thanks
