As said above I am looking for a compatible videocard/s for my old, heavy but trusty acer aspire 7730G since only after 7 years of use (heavy use) it just started to whine now and looks like old faithful needs a lift on that part.
I do not think you can upgrade your laptop's GPU.
Vast majority of laptops GPU can not be upgraded.
you are right on the upgrading part but what I was asking was other compatible GPUs since of course I can't put 1xx 2xx series GPUs on this old machine was thinking about the 9800M GT but im not sure since at the time that was the "IT" GPU for mobile from nvidia.
