Hi. I've just bought a Mac Pro to replace my iMac. The spec is: Mac Pro "Quad Core" 2.8 (Early 2008) * Single 2.8 GHz Quad Core 45-nm Intel Xeon E5462 (Harpertown/Penryn) processor * 12 GB of 800 MHz DDR2 * 500 GB + 320 GB (7200 RPM, 8 MB cache) 3Gb/s Serial ATA hard drive * Double-layer 16X "SuperDrive" * ATI Radeon HD 2600 XT * OSX Snow leopard I'm a complete newbie as far as Mac Pros are concerned. I will be upgrading to Mountain Lion as [I think] I can transfer the license from the iMac which will go back to Leopard when I sell it. I'm going to need two other things straight away: 1. Display. Ideally I'd like to include sound and iSight which I guess means I'm limited to Apple only and I need to upgrade the video card to one with Mini DisplayPort. Are my assumptions correct? And what is the best value card? I do a little gaming [Diablo] and quite a lot of photo editing but not video editing. 2. Storage. My iMac' 1 terabyte is already maxed out so I'm going to need to add some disk space. Is it true that I'm limited to 1 terabyte max disks? And is there anything I need to look specifically in disk drives? Is SSD a good idea and if so what make and capacity is the best value? Any help or other suggestions will be very gratefully received. Thanks in advance.
