That would be impossible because the small form factor of MXM-A limits dedicated RAM to 2GB.
See link below for all gaming MXM-A format GPUs. As stated the K2100m is derived from the GTX 660m (MXM-B) so for gaming purpose it would be very likely the K2100m is a bit less powerful than the GTX 660m.

The most powerful gaming GPU would be the Radeon HD 8750 and according to Notebookcheck they rank it below your current K2100m. They rank the K2100m near the bottom of "Class 1" mobile GPUs while the Radeon HD 8750 is ranked near the top of "Class 2".

It would seem that the most powerful MXM-A workstation GPU is the FirePro W5170M. Notebookcheck ranks it a bit higher than the K2100m. But that is based solely on specs alone since they do not list any benchmarks for it. Both of which are ranked below the GTX 950m.

Thanks for the info again. My wallet is kind of tight because of various things and I won't be able to get a whole new laptop unless I sell this and I'll still have to fork out around 1,000 us dollars for a gaming laptop with the specs I want. If you could recommend some laptops that are under 2,200 us dollars I would really appreciate it. Thanks again for all the help.
If you want a more powerful GPU in a laptop, then you need to consider buying a new laptop because you are basically have the 2nd most powerful GPU that can be installed in your laptop. The most powerful GPU that can fit in your laptop is not that much powerful and it is only ranked based on specs alone.
