SSD only helps load times, period. In games like Crysis it can stabilize fps somewhat since it often loads textures mid-gameplay, but I seriously doubt it would affect you in L2 at all (besides load time, which is blazing fast with my x25-m)
If you get a new cpu, stay the fuck away from that amd crap. Intels oc better, and they have more instruction sets (where they can be used - they will waste the amd cpu that can't use them in performance)
Also, if you want performance, don't use fraps, it's shit. Camstudio (free) and hypercam (set them to use huffyuv in ffdshow encoder) don't cause performance loss when recording a game - fraps LOVES to kill performance, and it has an AA bug with some older games like PW causing astronomical performance loss.
Hopefully camstudio will see improvements, its lack of configuration is abysmal.
