The NVidia GeForce 8800 GT in my early 2008 Mac Pro 3,1 just cut out. Or more specifically the fan no longer fans, and any activity that uses the gpu will crash the computer within seconds. I just spent about 2 hours trying to figure out what my graphics card replacement options are and I am completely overwhelmed.
Not only have I always been confused by graphics cards and which are better, but figuring out which ones will work with my computer has my head spinning. The video cards sold on Apple's website all claim they require a 2009 or 2010 model, though people with the same computer as mine have claimed to run the 5770 with no problems...
Anyways, I would appreciate any advice! I am planning on keeping this computer for a long time to come, so I'd like to go with the best upgrade possible (excluding anything too pricey - like the $1200 one on Apple's store).
Also, if it's relevant, I am currently running 10.6.8, but planning on upgrading to Lion anyway - so I could always expedite the upgrade if necessary.
Thanks ahead of time for any tips!
