In that cases having a very fast swap space in the Video RAM, in addition to the disk swap, would be a good solution. If you have a video card with so much excess memory, that you can use it for swap, then I wonder whether the video card has not been much too expensive ;-) How about spending $25 for another Gigabyte of RAM (real RAM, not SWAP) instead?
