MSI GX70 GPU Upgrade options

[Derpmaster69]

Grabbed an MSI GX70 off of FB Marketplace for 50 bucks. Has a bad battery and keyboard and has some white lines in the corners of the display panel. 

 

Specs-AMD A10-5750M with Radeon HD 8650G iGPU
            8GB DDR3L

            AMD Radeon HD 8970M/R9 M290x 2GB

            128GB SSD

 

After digging up some old posts in Reddit and MSI forums, I found that the CPU cannot be upgraded any further. The RAM can be upgraded up to 2x8GB 1866, has some sort of super RAID card to run 2 MSATA SSD's in RAID configurations.

Anyways, regarding the GPU I found nothing. It has an MXM-B slot and I was wondering what GPU's it can take.

PS-This laptop uses some weird "AMD Enduro technology" which I think is like SG but only for AMD GPU's. Anyone knows what GPU's my laptop could take?
