I've seen a bunch of sites that benchmark new hardware on gaming performance, zipping some files, encoding a movie, or whatever. Are there any that test the impact of new hardware (like SSDs, new CPUs, RAM speeds, or whatever) on compile and link speeds, either linux or windows?

It'd be really good to find out what mattered the most for compile speed and be able to focus on that, instead of just extrapolating from other benchmarks.
