Great, thanks for the advise. It looks like the lowest price on the 1GB version is $240, so that's definately pushing my budget. On the other hand, I could probably do it if I sell my 8800GT. Is it even worth keeping as a Physx card? Thanks again.
If you own or intend to get one of the 16 or so games that can actually make use of it then perhaps it might be, if not then ebay it and get some beer tokens back.
