I do not currently own a mac but am in love with the OS and really want to buy one. Im not really strapped with cash at the moment and I dont want the mini or an imac. I did some searching on ebay and found a mac pro priced at $1100. A1186 2x 2.0GHz Dual-Core Xeon (4-core) 1GB RAM 160GB HARD DRIVE DVDRW - SUPERDRIVE NVIDIA 7300GT My current computer is one I built a few years back and its specs are. AMD athlon 3800+x2 2 gigs ram Nvidia 9800GT My other question is in the future would I be able to upgrade the processors that are currently in this mac pro I might buy with quad core ones so I could have 8 cores.
