Hey guys, I have a decked out Mac Pro 3,1. I think I've reached the limit on its performance. I do video editing, and while its great. I will be working with heavier footage soon. I don't really have a budget for a nMP, also I love the mac pro's so I want to keep it strictly apple (no hackintosh). So I thought my best bet (to keep it easy on my pockets, and see increases in speed) is the Mac pro 4,1 to 5,1 flash, and then upgrade to westmere. Then sell my current mac pro 3,1 to make up for the costs. Couple of questions. 1. if I get a Mac Pro 4,1 @ Single 2.66, do the flash from 4,1 to 5,1 with netkas efi flasher, can I upgrade to W3690 3.46 Hex? - is it simple, as flash and swap? done? 2. If I get a Mac pro 4,1 @ DUAL 2.66, and do the same as above, is it as simple as flashing, and then buying two W3690's, and dropping them in? If anyone has a guide to this that is recent. I have found a couple, but they have missing pics, old broken links etc.
