I've heard mixed opinions on this. Currently I own an 8800gt that is 256mb. It was available for a few months when the 8800gt first came out and the 512mb version was always out of stock. However, now the 9800gt with 512mb is available for $100, and that is less than I paid for my 8800gt. Would the upgrade be worth it if I only play at 1360x768? I have: Dell XPS 400 Pentium D 820 3GB DDR2-5300 ram Thanks edit: I did a little more researching and I found the HD4830. Is that a better buy?
