It all comes down to how much on-board memory your card has. If it's an old card, it may be able to support some high resolutions but at the cost of reduced colour depth - 16-bit colour range instead of 32-bit - to fit within a limited memory capacity. I gather that the game prefers to be run in 32-bit but take that under advisement, I forget where I read that.

As a for instance:

800 x 600 x 16 = 7680000 (div by 1024 = 7500kb)
800 x 600 x 32 = 15360000 ( " " = 15000 kb)
1024 x 768 x 16 = 12288 kb)
1024 x 768 x 32 = 24576 kb)
1600 x 1200 x 16 = 30000 kb)
1600 x 1200 x 32 = 60000 kb

If I'm right and 1Mb is 1024kb, then that last one is approx 58Mb, so a 64 Mb card should be able to support it.

However - and I'm not sure this is still true - the trick with most vid cards is that they use half their memory to display the current frame on screen and the other half to 'assemble' the picture elements of the next frame to be shown in the background, then flip between displaying one or the other at whatever the current frame rate is.

If that's correct, then the maximum width x height x colour depth it will support is about half of what you'd expect of it. Like I said, higher resolutions may be available but only in reduced colours, or they may run okay for a time and then a hardware component on the vid card overheats from the strain, goes out of tolerance and the errors that generates crash the CPU.
