Hey, The first and the last windows desktop machine I will ever owned bit the dust. Thank god. But i need a desktop machine, and I should get a mac pro to replace it. (i needed windows for architecture programs, but since the move to intel...) So, my question to you all is... (i know so little about the mac pro's...) -how best to spend $1500-$2200 on a used or new mac pro machine? some things i need: i do rendering and 3d modeling often. I will likely use parallels and bootcamp. I can sometimes run computationally intensive programs like catia and maya, but not tooo often. sometimes i edit video. Lots and lots of images and image editing... usually i put my money towards monitors, but i'm happy with the two monitors i have presently. my peripherals are fine... i just need a new machine.... emphasis on RAM and processor, then video card, then hard drive... I want it quiet and to last at least 5 years... which mac pro should i hunt down? mac pro: dual core, quad core, 8 core?! thinking ram min of 8 gigs... but thats upgradable (so long as the slots are there)... want it to run quiet... videocard is good enough but not super duper.... thanks for any advice! r.
