Something like this is what I had in mind. (follow link to e-bay)

64 MB DDR (thats what I mean by LOW RAM)

That card model you are getting is more then 4 years old, and even then it was the bottom end of the pack. Having 64 MB or 256 MB RAM on it wont do you any good if the card cant even handle a single Vicky 3 class mesh (and it cant, i had one of those clunkers a long time back)
For at least half decent results you want to get something like a Geforce 6600 or something. Or the ATI equivalent.
