Recommended graphics card?

[Vince]

Hi there,

Vizard often crashes for me when I try and run the navigable window (by hitting F5). It does so on average once every three or so runnings.

After consultation with a friend, we believe the problem may be my feeble graphics card (32MB).

Can anyone recommend a decent graphics card in the 128 - 256 MB range that they have used with Vizard and can vouch for its utility?

I was running Vizard 2.51c but switched to 2.17 in a (failed) attempt to stop the crashing.

My machine is running:

Windows XP, SP2
AMD Athlon 2400+, 2.01GHz
480 MB of RAM

Any help would be appreciated, as my thesis work depends on my getting this up and running!
