how good of a graphics card. will 512 work or do I need higher
You want a FULLY DX9 compliant card.
If you want to really play it safe, get a DX10 card instead.
e.g. an Nvidia 8600 GT w/256 megs of ram or more is a good compromise as it is fairly inexpensive, but can be clocked up to speeds rivaling an Nvidia 8800 GT.
