Looking for advice on the most cost-effective way to convert my 2010 2.8 Quad to a Dual Processor/8-core model to increase longevity. OWC turnkey seems outrageous at almost $3000, and all the parts don't seem to be available from eBay, etc. Is there anywhere that sells parts, or better yet a kit at a more reasonable price? Would I be better off to just stick with a single 6-core or upgrade to a nMP and enclose all my drives using TB->FW800? Bottom Line: Really not wanting to shell out $3k if I can help it. FWIW: My usage is primarily video editing & audio dubbing/voiceover. I produce video training courses for health care systems.
