They went with the ATI 2400 XT and 2600 Pro. Low end garbage. # 20-inch model with 2.0GHz processor * ATI Radeon HD 2400 XT graphics processor * 128MB of GDDR3 memory # 20-inch model with 2.4GHz processor and 24-inch model * ATI Radeon HD 2600 PRO graphics processor * 256MB of GDDR3 memory See here for benchmarks and comparison to the Geforce 8600 GT and GTS. The ATI cards are outclassed. If they had gone with even the 2600 XT instead of Pro, I'd like it better, but this just sucks. So that about does it then...no gaming Mac unless you want to get a mac pro and try to get an 8600/8800 GTS to work in it. Apple, color me disappointed.
