I can't offer any experience on the ATI card. Which model GF4 do you have? I have had a GeForce4 MX 440 AGP 4x card in this machine for some time that I purchased on sale for ~ US $35. I have tested both GF 5200 and GF 5600 cards (the 64-bit memory interface models that retail for < US $100) and my 440 AGP card is significantly faster than both. If your card has a fan then you can probably use nvclock (from the livna.org repository) to boost performance 10% or more. (nvclock does not require a fan, but I would not feel comfortable making a significant change to a passively-cooled device that almost always hangs upside down). I was shocked that the "new" models were consistently 15% - 30% _slower_ in glxgears, Chromium, FlightGear, GL screensavers, etc. than the old, cheap MX 440 card. Even overclocked, the 5200 and 5600 could not beat the stock MX 440 frame rates. The difference was also consistent when installed in a Windows XP machine. So don't discount the GF4 card just because it is old. It seems that anything faster has a price tag > US $150 as well as a huge fan. The ATI's extra memory would be useful only if you play games that use lots of textures. Regarding relative graphics core performance, others will have to comment. Kevin Freeman
