Apple provides a couple bar graphs of gaming performance tests they've done with the iMacs which can be found here:
http://www.apple.com/imac/graphics.html
However, those results are mis-leading because if you read the print below the graphs it tells you that the ATI card used in the 20" for testing was the 128 MB version. I'm curious to see results for the 256 MB ATI card in the 20" versus the 256 MB nVidia card used in the 24". If anyone has first hand knowledge of or links to sites providing gaming results of the 24" iMac versus the 20"iMac with BOTH using their respective 256 MB cards, please let me know.
I want to buy one and am having a hard time justifying the price tag of the 24", but am willing to pony up the coin if I can see substantial real-life differences in graphics performance between the two systems. And please don't tell me to go to TomsHardware's VGA charts... Apple doesn't provide specific enough data on the graphics cards to know the EXACT specs of the cards in their systems. Also, I don't believe any of the cards on those charts are the mobility versions. If I am wrong their feel free to correct me in that assumption.
