I got my E2180 to 3.2ghz with a nudge of vcore and at this speed, it's much faster than an e4500 at stock even with the lower amount of cache. If you're up for overclocking, the E2180 is a tough bargian to pass up. But, on the other hand, for an extra $20 you can get the e4500 and OC that too. Welcome to the world of c2d I guess. 🙂
