I have the HD3300, which, is looking to turn out to never work.
I have decided to just by a dedicated card, because I miss OS X badly, and want to try Snow Leopard.

My main concern is compatability, what card would work out of the box? Which one is easiest to get working?
I need something that can handle WoW, The Sims 3, and any other games that work on Macs, near or maxed out.

My spending limit is about $100.

Thanks.

I can also go NVIDIA, I've had both and love them. lol

HD4850

Agreed. It's a damn card, but dont make the same mistake I did by getting the Saphire 4850 dual-slot cooling DVI-HDMI-VGA. It's like pulling teeth to try and get it to work. Apparently all other 4850's are easier to get running

I'm studying components to build up a hackintosh for dual booting OSX (ordinary use of PC and iphone programming) and Window$ (for playing).
I'm planning to buy a Radeon HD 4870X2 ... anyone has info about it and snow leopard? Ever tried it?
