I am about to buy the Nvidia 5900 card but i noticed the 5900 with only 128mg of ram compared to 256mg ram is almost $300 cheaper. Can anyone help me out as to what the benefits will be if i buy the 5900 with 256mg ram over the same card with only 128mg of ram. This seems so far to be a question which no one can give a definitive answer to. Any help would be gratefully accepted. Andrew - Australia.
