Last week, I purchased a used 2008 Mac Pro 3,1 off Craigslist. I know it's old, but I absolutely love this machine - dual 2.8 Ghz quad-core Xeons, w/16gb ram. I put a SSD in it, and this thing absolutely screams...especially for 8 year old hardware. I also put a graphics card from a Windows PC (Nvidia GeForce GT 610 w/2gb VRAM) in it, which leads to my question: It still had the original Radeon 2600 XT installed, and I wanted a bit more muscle. Since the GT 610 is a non-EFI card, I lose the boot screen, which I realize is completely normal. In a perfect world I'd like to get the boot screen back, but I have zero interest in buying a new graphics card. I realize this may be a dumb question, but is it possible for me to re-install the Radeon 2600 XT and run it side-by-side with the GeForce GT 610, or will that cause problems? Furthermore, if it IS possible, I assume the monitor would need to be plugged into the Radeon, so what would I need to do within El Capitan in order to use the GeForce? Thanks for any comments, this forum has always been very helpful to me!
