What is the recommended minimum requirement for 'ultimate' video settings (all effects on)?
I have a Linux rig, so NVidia is the only option I will consider.

Additionally my setup has to cater for video HD playback @1920x1080 and passive cooling is a must! (silence is golden).
I consider Nexuiz to be the flagship game of choice for my installation, so 3D performance
is based on its requirements.
In practice, I am too close to my large hdtv to game at 1920x1080 (but playability kudos could apply!

I was thinking maybe a Geforce 95 to 9800GT (PCIe) would be great (DVI + SPDIF to HDMI).
Obviously I would expect the above cards to be good anyway, but smooth 60FPS at max
settings? What do ya reckon?
