Me I have Windows XP Pro (Yes, I like It), One of these days I'll just have to bite the bullet and get a New CPU (Athlon XP 2800+) and a Motherboard (Epox 8k5a3+) to upgrade from My current system which uses a K6-3+ cpu (475Mhz is stock) @ 550Mhz on a Gigabyte ga-5ax r5.2 motherboard. I know It isn't even close to being as fast the systems mentioned here, But Hey I'm broke. Although that might change soon hopefully. I'm thinking about water cooling My next motherboard though, But then I like overclocking. My AOpen GeForce2 MX is overclocked to 235/215Mhz(240Mhz is max for the GPU though) with ramsinks and Artic Silver 2 between the stock heatsink and the GPU (Stock is 175/166Mhz).
