Eh.. Another tweaking thread is it?

Hi!! Sonar is working nicely for me. It's not without a wrinkle yet but i feel I'm in control at least Anyways, I was just wondering if anyone knew of any tweaks I could do to Win7 for better performance with Sonar, or point me to a site or something that has a few handy tips? I did my current install from scratch and I'm now completely in the 64-bit domain. And although I'm not suffering from poor hardware, I have some mean projects going on and could use a little extra grunt if possible. I haven't done any tweaks to Sonar (except the obvious - ASIO drivers, buffer sizes etc) or the OS. See my specs in sig. Any tip will be greatly appreciated. If there's nothing to tweak I wouldn't mind knowing either I tried a quick search but don't have time to read it all. Deadlines, clients and very annoying people breathing down my neck! Thanks
