I'm very interested in this thread as I am (was) considering a 3.0 ghz PIV with HT technology and 1G of ram. Right now I run P5 on a 1.7 ghz PIV with 512 ram and it sounds like I have less problems with speed than you guys do! Maybe I'll just add more ram and forget about new fancy Hyperthreading machines, especially since the only purpose for getting it was to increase the speed of P5! My understanding of this new technology is that it simulates having two processors.......maybe that's why P5 is only using 50% of CPU.
