In an effort to save money, I added an SSD to my 2009 13" MBP. C2D 2.26GHz, 8GB RAM. It doesn't really help. My CPU is the bottleneck, it still pegs, and the CPU still runs hot. I think I just need more CPU firepower. Also, btw, the move broke my MS Office license and has created issues with iTunes and some other apps I'll have to spend some time on, figuring out how to re-establish the license. Thought I'd pass this along for anyone who might be considering the same.
