Running the retail UT with a K6-2 400, FIC 503+ MB, SB Live Value, 3DFX Velocity 100, 196 megs of RAM.
No problems at all runs nice and smooth at 800x600. Have spent lots of hours over the holiday playing it on both the Internet and home LAN. Assault rocks and I get wait to upgrade to a Athlon 500/Ultra TNT2 in about a week to crank up the res/32 bit color.
