As the title states, I am sold on the iMac (24") for my next computer. I currently have a 13" MacBook from March of 2008, but the lack of a video card makes playing games a bit of a drag. I have been looking into the iMac since I got my laptop, but I have been hearing some problems related to both vid cards (NVIDIA and ATI) in regards to playing Warcraft. I've searched thru google and found thread after thread on both of them causing errors and gameplay issues, but it seems that it's mainly on Vista systems. If someone could give me advice on which card to get: NVIDIA GeForce GT 120 256MB NVIDIA GeForce GT 130 512MB or ATI Radeon HD 4850 512MB and weather or not they cause issues in Warcraft with Macs, it would be greatly appreciated.
