It *might* be possible to use a 750M provided they don't make major changes to the body design of the Ultrabay in the latest Y500. It is possible to use one GPU from the Nvidia Control panel (i.e. install a theoretical 750M then switch to it as the primary GPU for games) that being said, a 750M may not have the performance of a SLI 650M set-up. It will most likely be around a 660M's performance.

Is there any way to overclock the graphics card? I don't know if anyone noticed, but overclocking via Nvidia Inspector actually doesn't increase the max clock. It says it does, but if you check the usage while gaming, it's locked at 790Mhz.
