hey guys im in the market for a macpro. now my sister is gonna purchase my old desktop, its a hp m8120n with a quad core q6600 2.4ghz with 640gb hd space and 3gigs ram. shes gonna pay $500. my main usage out of this computer is production and remxing with acid pro. this program is only useable in xp. right now i have no issues running large projects, and from my understanding a macpro quad core model has even more power then my current pc. so i should be safe right guys? now i do want to still run osx of course but i want my xp partition also, is it possible to to partition it to another drive beside the main one? also i know there are supposed to be updates etc etc, but i dont want to spend 3k for a macpro because i dont see the speed bumps of the new macpro really benefitting me when a q6600 is already doing more then its share of the job, but now i wonder if the new ones come out if the price for the old quad core 2.8 will be cheaper? or go on clearance? i found a macpro on j and r.com for 2,279 free shipping no tax and its basically the model i want, anyone know of a place cheaper? http://www.jr.com/apple/pe/APP_MA970LL1/#productTabDetails also if there is a new macpro on the way anyone know if they will keep quad core configurations or will it all be octo core only? do you guys think the quad core macpro is a waste? i want this machine to last for a while, probably the last addition to my small home studio.
