Geek guys out there... help! One of my MacPro's (2008-09 tower) allows me to install Mavericks but won't allow me to install the upgrade to FCPX 10.1, it requires a new video card to allow installation. Ok... so the new video card that will run it (EVGA : VIDEO CARD GTX680 MAC 6008MHZ 256bit) will cost $700... that's ok, but does it make sense to spend that plus add more Ram to the existing 6GB?? I'm looking easily at $1,000 to run FCPX 10.1., hopefully comfortably enough for my assistant to cut with proxy footage. Am I better off taking that $1k and adding another $500 and buying a new Imac or laptop for $1,500, or even going for the new 15" 2,000 laptop?? Note that I do love the fact that I can put 4 HHD's inside this VERY reliable though older machine.
