I have Poser 4/Pro Pack and Poser 5. I am thinking about getting a new video card for gaming purposes. 1) Will a new video card, such as a GeForce FX 5900Ultra 256MB make any difference in using the programs? 2) Does Poser care about video speed? 3) Does Poser care about video memory? 4) On a side note, I have 1GB of DDR, will adding more make any difference? Using Windows XP.
