I own a first generation Mac Pro with two CPUs @2,66Ghz, 16GB RAM and an Nvidia 8800 graphic card. I have about 3000$ to spend on a new computer, so I am planning to upgrade to the latest Mac Pro 1CPU Nehalem model. I am using my Mac Pro for a lot of things, like Internet browsing, email, video editing with Adobe Premiere for my home made films (nothing on the pro level), video streaming to my PS3, basic photo editing and other typical computing tasks. Nothing major here... I like the expandability of the Mac Pro, so please don't tell me to get an iMac. The question is, do you think that such an upgrade would be worth it? My main problem with my current Mac Pro is that it uses 32bit EFI and most probably it won't be able to run the next Mac OS X version. Thanks for your suggestions.
