The clawhammer FX-55 wont overclock well at all, and is SSE2 comapred to venice SSE3
Basicly if you buy a clawhammer CPU, your buying 2 year old technolagy, when with a little overclocking a 3000+ can beat out a clawhamemr.
Oh yeah, venice's use ALOT less power, you will notice your power bill's will be lower
