I'm playing currently @ 640x480 med qual.

Good enough for me really. Honestly, does pitch black look that much better @ 1600x1200 than it does @ 640x480? Didn't think so.
More seriously, I'm planning to OC my system again in the near future, and possibly swap memory with another one of my machines to have 1GB of XMS3200 dual channel.

Waiting for the RTV to cure on my pump/airtrap.
Just took the machine apart and cleaned it again (dust had plugged both the CPU and NB fans, stopped them completely...

not a problem on the vidcard--sink only, no fan! ) and realized that I only had the ATX power connector run to my mobo. Will see how high I can clock it with the ATX12V connector plugged in...I've also had problems with graphical corruption (in 2D) and GPU resets...RMAing the card as we speak...back to GF3 Ti200 temporarily
