Hello, I am going to be placing an order for this new MacPro: One 2.66GHz Quad-Core Intel Xeon 3GB (3x1GB) 640GB 7200-rpm Serial ATA 3Gb/s ATI Radeon HD 4870 512MB One 18x SuperDrive Apple Mighty Mouse Apple Wireless Keyboard (English) and User's Guide AirPort Extreme Wi-Fi Card with 802.11n I was wondering if this machine would be enough for my needs? I do most of my work in OmniGraffle, OmniOutliner, and iWork (Pages). I also want to be able to run Snow Leopard and Windows 7 when they are released. I only play games occasionally. I would think a machine with these specs would be okay for what I use it for, but Im really not sure, which is why I need some advice. Im especially concerned about the 3 GB Ram. Do you think I will need more ram to run Snow Leopard, Windows 7, and an occasional game under Windows? Will I experience a major slow down with this little ram? Thank you for your help!
