How much RAM does my card have?
The information will be in /var/log/Xorg.0.log somewhere (your X video driver knows more about your card than anything else does), but the exact string varies depending on your video driver. These searches generally work:
grep -i kb /var/log/Xorg.0.log
grep -i ram /var/log/Xorg.0.log
Is there a simple benchmark I can run?
- glxgears — don't use it for benchmarking, it's buggy, it counts non-rendered frames in the frame rate, which means that covering up the window results in >1000fps
- xscreensavers — many have a -fps option
- if you have any 3D games installed, often they'll have an FPS indicator
