Hi, I'm Paolo, and I'm Italian, so sorry for my bad english... I'm going to buy a brand new Macbook Pro 15" 2.8Ghz with integrated NVIDIA 9400M chip + the discrete NVIDIA 9600M GT graphic cards for my University Career and I'm reading on the web that there's already a feature (on Leopard) that switches in real-time the GPUs in order to save battery life without logging off choosing one single chip at time like before, but there's no SLI function yet. I was wondering if and when an Hybrid-SLI technology will be available both for Leopard and Windows (for gaming). I'm going to install Snow Leopard and create a second partition of Windows 7 x64 via Bootcamp only for Gaming (Crysis, Far Cry 2, The Orange Box and others) and it will be awesome to enable some sort of SLI, with both of GPUs working togheter, increasing framerates and visual quality! So, there's some news or update about that? It's just a matter of time and software or the hardware is not capable yet? Thanks very much!
