I know we don't know the exact benchmarks yet, but people seem to think the GPU almost won't handle the retina resolution. And will be really slow when using scaled mode (although Apple says it will do up to 1440x900). So... How bad is it? Won't I even be able to play a 2D game from app store? Like a TD or so? Will it play streamed 1080p flawlessly? People are scaring me when they're suggesting the rMB's GPU is lowest of the low.
