Not sure if they’ve improved much since then, but my experience with SSDs has been that they’re significantly slower than disks. That was a few months ago, though...
There is one off brand name SSD in the case and it gets no software benefits.
Regardless of that, clocking my i7 CPU to 4.2ghz from even 4.0ghz gives a large increase
in speed that can be seen. The bottleneck is still the same for Video cards, and it's
always been the CPU.
