There are so many new microprocessors coming out that it's difficult to decide whether to upgrade soon, or wait. Intel's Harpertown (server) and Yorkfield (desktop) chips look very good. But Nehalem will be coming out next year. It will have an onboard memory controller and up to 8 cores per die with two threads per core. That's 16 threads on a single chip! Decisions, decisions. For now, I think I'll wait until the dust settles. The dual Clovertown rig is doing really well. Load temperatures have dropped a lot since the cooler weather arrived.
