Yep, only if CUDA is used by apps you need the CUDA install.

It has no effect for OpenGL/Metal drivers. OpenCL (its like CUDA but for AMD and! NVIDA)  and "normal"  apps.

Yep, but you must buy that bigger sized VRAM chips, beside unsolder/soldering.

For low cost gpu cards no value (chip cost, shipping cost and! they are after that as slow as before, because gpu same!) - more an "we can do that" :)

Older NVIDIA gpus (havenĀ“t some newer gpu features)  need older/other CUDA driver for my knowledge. Take a look at the official CUDA download site.

Note: this driver does not support the older generation GPUs with compute capability 1.x. To find out the compute capability of your GPU, consult the following links:

You can not upgrade  any memory (VRAM)  to an grafikcard.

With less game usage or only casual 2D, small 3D games usage 1 GB VRAM is enough. 

Avoid old DDR2 VRAM cards. THat slow VRAM makes the older gpus even more slow. Take DDR3 or DDR5 VRAM (not DDR2) - and better less VRAM1 GB with faster DDR3/5 as more 2 GB VRAM with slower DDR2 VRAM.

Some older GPUs are available with 2 GB VRAM but slow DDR2/3 VRAM - better buy the 1 GB DDR3 / DDR5 VRAM version. For gaming - there its good to have more VRAM - the old gpus are to slow,

doesnt matter 1 or 2 GB VRAM.


Speed hint:

If you not already use an SSD as HD type, buy one. This is much faster in all day usage (booting >= 3 times, App start >= 2 times, App usage often better like Safari browsing).

128 GB SSDs are worldwide now cheap - and is normaly enough in combination with an HD (500 GB .... 2 TB) where you have place for big data (Musik, Video,...).

I use Nvidia GT 740 (Kepler GPU) which works OOB (disabled grapic injection in chameleon, not needed) . Before that i had an GT 640 - also OOB, 740 is about 20% faster.

Works with OS X drivers and! NvidiaWeb.

I have also old 775 GA Mainbord with Quad 8400 cpu.


I would avoid Fermi (working but some freezes, more power consumtion) and Maxwell GPU (you need NvidiaWeb driver - problem of updates and not full compatible - we wait for Apple Maxwell/pascal drivers)


So look for an Kepler GPU type - depends of speed and price you want to pay. Used ones are also available :)

Highend Kepler GPU type would be not a good deal, because you would need then also much faster CPU to get full speed advantage.

GT 640 (Kepler) / GT 740.

GTX 750 Ti maybe also good , faster than GT 740 and not oversized for the low end CPU.


Here List of GPu type 600 , 700 - because its really difficult to guess which card type has which gpu type (Fermi/Kelper).
