LINUX X64 (AMD64/EM64T) DISPLAY DRIVER update for Unix?

Hi,
Apparently Apple no longer supports the NVIDIA GeForce GT 330M 256 MB, and has not updated the driver in their OS to reflect its recent update in LINUX (below).

What is a macbook pro user to do? I know my MBPro is now 5 yrs old - but with an i5 and 8Gb RAM I would think I shouldn’t need to throw shell out for new just yet?

Currently running any video appears to disrupt communication between my Vizio E240AR and MBPro - El Capitan OS ( with NVIDIA GeForce GT 330M 256 MB). Can you guys talk apple into writing an updated driver / patch that addresses the bug described below? I believe this is the issue.

Version: 340.96
Release Date: 2015.11.16
Operating System: Linux 64-bit
Language: English (US)
File Size: 66.59 MB

Fixed a bug that could cause texture corruption in some OpenGL applications when video memory is exhausted by a combination of simultaneously running graphical and compute workloads.
Added support for X.Org xserver ABI 20 (xorg-server 1.18).

Would something like this reduce the strain on memory and eliminate the issue?

My RAM is already at max 8GB, would upgrade to Solid state hard drive reduce memory strain and issue?
