She has 8 Core, 8GB RAM, Raedeon HD 4870 graphics, Windows 7 64 Bit via Bootcamp. It's a beast. It runs the benchmark fine and gets pretty decent scores, but the sound on it doesn't work. So we were thinking it could have something to do with the sound, but I don't know why that wouldn't even let the beta run at all. I downloaded the latest ATI Drivers (10.7) yesterday, but that didn't change anything.
