Jammer

Currently, my Lenovo U530 Touch is my only option as a laptop to explore adding an eGPU to. After a fair amount of searching, I'm not finding whether this is even an option for this laptop. In short, I'd like to make it work if possible but am unable to find out if I'd be wasting my time resourcing the parts needed. MB was changed due to a faulty drone connection that fried it and it now runs a slightly better Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz instead of the i7-4500 @ 1.8. Any help in the right direction here would be great. The dedicated Nvidia 730M 2gb card isn't cutting it. I can barely even run CAD programs at desired rendering with it. Thanks
