Let me tell you my experience with both Northwood and Prescott: I first got the Prescott think oh wow yeah 1 gig L2 cache. But unfortunetly it did overheat a little bit (nothing damaging). I returned it (they actually took it back) and got the Northwood. Since then I have great temps, everything works just fine and now I have the thing oc'd to 2.8 from 2.4. I'm very pleased with the choice I made (with the help of others as well)
