I'm working on a Mid 2010 Mac Pro and was wondering what I could do to update it. Its purpose is a presentation and multimedia machine for a church. Lately, it has seemed much slower than what it should be and isn't meeting the demand. Here's the basic run-down: 2.8 GHz Quad Xeon 8GB 1066 MHz DDR3 ATI Radeon HD 5770 1GB The main thing I am looking to do is upgrade the graphics card but I am unsure of what I can put in it. I see that it takes a PCIe slot, but does this mean I can put just about any graphics card in it or will it have to be mac specific? I'd also like to make sure I can run three HDMI outputs from this. I'll take any advice/suggestions on this. I'm also looking to put in an SSD (probably Samsung), and put in 16 GB of RAM. Would it be recommended to put in a higher speed of RAM such as 1866 MHz? Any advice on what should be done will be greatly appreciated.
