When I saw PS at E3 2001, it was running on a P3 with a GF2, but that was "Pre Alpha" so a lot has changed since then. Hell that was even before Dave G was with PlanetSide so it
was (<--note my use of italics. It makes me cool like everyone else
) a very long time ago.
Me I caught the upgrade bus a while back and took it to the GF4 Ti 4400, and Soundblaster Audigy stations. I still mightget a new processor though. 1.4 Ghz just doesn't seem fast enough any more.
