I currently have an early 2008 mac pro 2x2.8 quad core. Should I upgrade this mac or wait for the new mac pros? Upgrades 4x 1TB WD Cavier Black internal hard drives $320 8GB ram $275 5870 ATI video card 450 Total $1045. These prices are rough and could change. Seems like a lot of money for a 4 year old machine. Any thoughts on this? I realize I could shave some off the cost by going with a cheaper video card or using a PC version and flashing. Not sure I feel confident the pc video card will just always work though. Thanks for any opinions.
