I still remember their last video card (technically not a gpu since it's not that powerful) it's was on pat with a Riva 128. I had an 8mb model, agp 2x card. I played games like diablo 2, Warcraft 3, Starcraft broodwar, counter strike 1.6 (and of course half life), shogo m.a.d., tachyon the fringe. It handled those games well enough.
It was funny gaming with that in CS1.6. I remember the stress from processing the smoke effects from a smoke grenade would eventually heat the heatsink enough to cause the thermal glue to drop the heatsink. I'd hear a clunk just before fps tanked to single digits (smoke effects always slowed it regardless). But it never crashed, I'd just stick the heatsink back on and the fps would go back to being tolerable lol. I eventually zip tied a socket 7 heatsink fan cooler to it. I still remember the system specs, mostly
AMD K6-2 550mhz
2x 256mb pc133
8mb i740 vga
20gb Maxtor fireball ide
98se and later xp
A 3com 10mb nic (dsl was about 300kb/sec so it was enough)
Probably the first pc I browsed TPU with, I'll be rebuilding a similar system soon with a voodoo3, better hard drives, and dual boot win 98 and xp
