Sure, there would be a heck of a lot of variables to take into account, and it might not be possible to get all of them working. I'm just looking for some sort of way of determining what sort of CPU/GPU increases could improve you to beat a certain score, or how many point CL3 over CL4 on the RAM is going to give you etc.

If not a program that takes all into consideration, maybe people can post this sort of info from experience?

e.g.
CL3 vs CL4 vs CL5
DDR667 vs 800 vs 1066 etc
3600Mhz - 7 x 514 FSB vs 8 x 450 vs 9 x 400
GFX - GPU increases vs RAM increases?
