Hello all, I am looking for a 4 or 8GB video card new or used for my 2009 Mac Pro. I was thinking about getting this: https://www.ebay.com/itm/XFX-Radeon...236870&hash=item21490fc8bd:g:jr8AAOSwr3xbs3QG But I think that there are some power draw issues with this particular model. I only have a budget of $200. So, I was wondering, what are some popular 4GB and 8GB cards people use in there setups? I know that the Sapphire Pulse series is very popular and works well for mac pros. Also, having metal support would be a plus. I was considering Nvidia but it looks like I would need to install web drivers which is causing issues for some people. Ideally, I would like to not have to install drivers for the Mac because if the OS updates, I would like to continue to use the machine. I am having a bit of a difficult time with this because there are so many caveats with the graphics card in mac pros. Thank you.
