I currently own a 2009 2.93Ghz 8-Core MacPro with 26GB RAM, ATI 5870 1GB, and 3TB Internal HD's (non-SSD). One 1TB HD is boot drive, another is Time Machine for boot drive, third is secondary data drive for whatever. I also own two external 4TB GRAID's (one to use, one to backup). For those I use FW800. The current desktop is really fast and wonderful. It gives me no trouble, runs quiet, etc. I do web design, graphic design but more intensive things like video editing (1080p mostly), motion graphics, DVD authoring, etc. I render video often and this machine is the fastest I've ever used in that regard. I look at the Geekbench scores for a machine like mine and see that although "faster" the gap is closing between my current machine and newer laptops and iMac's. I realize the word on the street is new 2013 MacPro's but I'm not entirely sure it's necessary for me. Although the Geekbench scores are higher, in programs like FCPX that utilize the GPU's so much for final export (and realtime performance) I wonder if the new iMacs that just came out beat my current machine? I think the MacPro I have is still better for continual heavy lifting, but I do wonder if the newer GPU's combined with Thunderbolt HD's in a new iMac will best this machine overall when it comes to video editing and final rendering. If I sold the current MacPro I could probably get about $3000 for it. My current 24in Display would just have to go sit in a box and probably couldn't be sold for more then $50 since displays hold no resale value really, especially older ones. I would need to buy a few accessories to use the iMac like a Thunderbolt 4TB GRAID ($600) probably (unless I could find a FW800 to USB 3.0 adapter for my current 4TB GRAID's which would allow me to use current HD's but not give speed benefit), and something like a Blackmagic Intensity Shuttle so my edits can still be pumped out to my Production Monitor for color correction. Odds are too if I got the iMac I would want it fully loaded. What do you current MacPro users think? Just keep what I got for now? Sell and take the plunge? How would you expect my current machine to stack up performance wise? I feel like the major difference here would come in if I went Thunderbolt, and the possible increase in GPU performance, but there isn't really a way to compare them at the moment.
