Indeed. Perhaps phrased wrongly. Apple's most likely card for an upgrade is the GeForce GT 130M (the mobile version of the iMac card). It's a little bit faster than the current card, but nothing spectacular (maybe 15% better). Over on the ATI side you've got the faster HD 4650/ 4670 and the 40nm 4830. Given Apple's current love for NVIDIA, the Radeon cards may not be used.
