I did more reading just now and wish I had done more research before I bought. My Windows machine is just in such bad shape that I was waiting for the new Mac Pro to do an upgrade. I use a iMac at work so I am fairly literate in OS X but know little about the Mac Pro. I chose the stock out of the box $2799 Mac Pro. Now I'm seeing most people are talking about the NVidea 8800 card. I know there are a lot of card options, some even over $1000. I'm also not interested in having two video cards in my system but I see his is just $200. I know it has double the memory but what other reasons are people making this choice? For my use this is for home use but also for my fiancee who has a home office. It kind of will be a jack of all trades from the simple such as mail, ical, iwork (pages and numbers), some office 08 work such as Powerpoint, Word, and Excel, Safari browsing, etc. For the more intensive, I do a lot of work at home in ebooks such I'll be using Adobe CS3 (Acrobat, PhotoShop, inDesign, and sometimes Illustrator) and also I'm just starting to get into desktop video such as doing Final Cut Pro Studio. I do freelance work and am getting a HD Camcorder shortly so will be doing HiDef. Because of this I went with 8Gigs. My fiancee will use it also so frequently there will be 2 ID's logged on and also I'm a big multitasker switching data between programs, copying and pasting, etc. Now my fiancee is a gamer but he has his own Windows machine. He already wants bootcamp on here but honestly I always have programs open so prefer a solution like Parallels. The only game he really likes is flight simulators and he's looking at X-Plane for the Mac. Now that I've said what we use it for, would it be worth the extra $200 of the card or is that better spent elsewhere? I know I already ordered but even if I decide later can I simply add the 8800 card and can I just purchase anywhere or do I have to purchase from Apple? Now my other question is about Hard Drives. I also ordered the stock 320GB drive and was actually told I'm better off doing that because I can buy a lot of accessories that are better and cheaper elsewhere than Apple and my fiancee is willing to help with the upgrades. I actually want to go with two hard drives. I want to replace the 320GB with a 750GB-1TGB drive that is used as a system drive and then get a 2nd drive that is more like a data drive. I have looked at Maxtor a lot and heard they are good and actually heard I should stay away from Seagate but I'm hearing a lot now about Fujitsu and Western Digital and saw that even their Green Power drives are good. Any suggestions of a good hard drive? Once again I apologize for all the questions from a Mac Pro newbie. I appreciate any assistance with this.
