I have the 2 x 2.8 GHz Quad-Core Intel Xeon, 4 GB 800 MHz DDR2 FB-DIMM, NVIDIA GeForce 8800 GT 512 MB, 500GB 7200RPM, 1TB 7200RPM. I definitely need more RAM, one of the original sticks (1GB) flawed itself a few months back and since it has to be an even number I lost the other 1GB as well leaving me with 4. My work is very photoshop heavy and I will be getting into After Effects, FCP/Premier very soon for 2.7k footage edits and some Cinema4D 3D work (motion graphics). My dilemma... RAM for the 2008 Mac Pro is ridiculously expensive and only 800Mhz (if that makes any difference). I also was wanting to buy a 27" screen because my 21" is just too little real estate for my needs. Would it be worth buying lots more ram for probably $300 or so and a new GPU $500 I think for the 5870 which is only 1GB and already pretty extinct, add a 3G SSD or should I go for the new 27" iMac paying about $1500 more than the upgraded Mac Pro route. I am actually leaning on the iMac route because it will last a lot longer than if I upgraded my Mac Pro (I think) and will be somewhat portable (compared to my MP). Not that I need portability but it is always a plus. Also USB3 but I think that is not a must for me. Thoughts? Thanks.
