Hey guys, I've been going through the forums, but I'm having difficulty finding a clear answer. I have a 2 x 3 GHz Dual-Core Intel Xeon, (1,1) with a GeForce 7300 GT in it at the moment, and I'm trying to find a compatible card that is Open CL capable so I can run Final Cut X. (Under Lion.) For instance, will a flashed nVidia 8800GT graphics card, PCIe card fit in that? I've heard both positive and negative about the GT120 sold by Apple as well. Any and all suggestions are appreciated. Thanks!
