I Have a Pentium 2 350 MHz and 320 MB of RAM. Xp Runs like a dream compared to the P4 HTs we have at my school. It runs faster and more stable (behind a hardware firewall- linksys) than my 98se and Me setups on identical computers. They all are Gateway E-3200s I aquired after a local school upgraded they're computers. I have the same hardware, memory sticks, and use the same power outlets.
