Yup... having a second hard drive allows you to move the page file to a separate drive which theoretically could increase performance but I can tell you from experience you won't notice the difference.
The only way to bring up that score is to install a faster hard drive such as a Velociraptor or an SSD. I personally have a Velociraptor but was very disappointed in the very slight performance benefits it brought to me. My money would have definitely been better spent on a better video card instead.
SSD drives can allow you to boot and load programs EXTREMELY FAST but unless the program you use constantly accesses the hard drive (Aces High doesn't) then you won't see any performance benefits after that. There are still a few issues with SSD drives with longevity and compatibility that are gradually getting worked out and while they've come a long long way I still don't feel they are nearly as reliable as old school hard drives.
I've heard that SSD drives bring a HUGE improvement to movie editing and CAD (3D) design applications, and they definitely bring a HUGE improvement to many gamers' egos and bragging rights but if you don't do movie editing or 3D design on a regular basis, I personally feel that once the coolness factor of windows booting a just a few seconds wears off you might end up regretting the decision to purchase one.
But if bragging rights and benchmark tests are important to you or if you just want to play with one then go for it!
