Right now I'm still running on my 2 year old GeForce 4 Ti4800SE.... due for an upgrade to a sexeh 6600GT in a few weeks time. But until then, my choice in games hasn't exactly been "cutting edge"

Right now I'm playing:

Quake 2
Descent ][
Soldat
CounterStrike-Source
Half-Life 2: Deathmatch

And occasional bouts of ZDoom.
