This is a good deal because AMD no longer makes these guys. It has twice as much cache memory as the AM2 X2 CPUs on the market now, and the same cache size as the FX CPUs. It's multiplier is 10 and OCs very well if you have a nice motherboard. (see my signature)

AMD stopped making the 1MB cache X2 CPUs to cut costs since they're now trying to out-value Intel. I've seen benchmarks where the larger cache alone allows for a7 to 10% bump in performance.
