I am thinking I should upgrade my ATI 9600XT card in my G5 (see sig). So I want to buy a card that is not on top of the line, but it will hold me for some years and games to come. I was originally thinking about ATI X800XT, but I don't want to spend that much money. I was thinking about nVidia 6600, but I get confused... 1)The nVidia 6600LE is sold separately or is just a Built-In option? Same question as nVidia 6600. 2)As for ATI... I have only seen ATI X800XT for sale on applestore. But I heard there are other cards in sale, such as X600XT. 3)One final question: What are the best graphic card models currently for Mac from both ATI and nVidia? Links and prices are welcome... Can you inform me on this matter, and please, if it is possible, include prices in models you recommend me.
