I just ordered the 8 core Mac Pro with the following configuration: 2 - 2.26 Ghz Quad Core Intel Xeon Nehalem processors 12 GB (6 x 2 GB) RAM 1 - 640 GB HDD ATI Radeon HD 4870 Graphics card 512 MB 1 - 18x Superdrive Airport Extreme Wi-Fi card I am making the switch from a PC and have quite a few questions about where to go from here. I plan to use it mainly for video editing, using both my current Sony Vegas software on a Windows partition and also trying Final Cut Express hoping not to have to make the switch right away to the pricey FCP, though I'd like it. I was planning on purchasing VMWare Fusion for running Windows and then buying Windows Vista Ultimate. Is that my best option for running Windows? Right now on my HP laptop I have Windows Vista Home Premium 32-bit and on my HP desktop I have Windows Vista 64 bit, not sure if it's "home" or business or what as I'm not home now and won't be for a few days. My understanding is the Vista that came with either of those machines will not allow me to install it elsewhere. is that true? I have a shiny new 24" LCD monitor for my HP, can I use that plug and play with the Mac Pro and I would like to add a 2nd monitor. Will the one ATI Radeon card support that or do I need another card? If the one card does support it would it run better with another one anyway. I don't understand the multiple graphics card thing. I just got the standard hard drive in one bay but want to upgrade the memory as my AVCHD video will quickly fill up the space. Can anyone tell me exactly what to buy that is compatible and from where. I also do not understand the boot disk vs scratch disk that I am reading about and also should I save one drive just for back up? Should one (the boot drive, or main drive) be a SSD? If so any recommendations on that? What would that do for me? They seem expensive but it may be worth it. I did upgrade the memory to 12GB as the $270 it cost seemed like a good deal (from Crucial I had seen a 6 GB kit of 2GBx3 for $171 and a 4GB kit of 2GBx2 for $114, that would have been $285 for just 10 GB. My question is if I want to add more RAM now I think there is 8 slots, do they ALL need to be 2GB each and "match" or could the last two slots be something else? Also I heard something about the DDR3 working best in 3s. Does that mean I should have only the 6 sticks to get the best performance? I think that's it for now. I am pretty new to video editing and so haven't learned all the lingo. What I do know is that while editing and especially while rendering my Vegas program would sometimes shut down every 5 minutes and then take about 20 minutes to reopen due to the slow "building peaks" process for all the media attached. And rendering was of course such a nightmare I wanted to toss it out the window. Oh, one more thing...I also read I can wire a network (I'm currently wireless) and then farm out the rendering to more than one computer. Can I do that between the new Mac Pro and my Quad Core HP? Thanks for any advice you can share or if you have ideas I haven't thought of.
