I am looking at buying an iMac, but for Windows use only. Really, the only comparable all-in-one desktop is Sony's, but it still has an inferior graphics card and screen. Am I crazy for considering buying an iMac for Windows use only? Does anyone else do this? Are the drivers for Windows on the new iMacs good? Are there any restrictions? Is it possible to install other graphics drivers from AMD besides the ones Apple handpicks for you?
