Need some advice please, considering a Mac for webdesign instead of a newer windows pc. Question is are there and big differences in site creation with one vs the other system. I am tired of my Dell locking up and being slow, using winxp pro sp2 with 2 meg of ram. Any suggestions on what mac or win machine may work best? What about processor for win machine, do I need a 64 bit processor, xeon, or what? Is 4 meg only good with 64 bit processor and winxp pro 64?
