I forgot about EFI and TPM.No.
For all the reasons Eidorian mentioned plus the fact that only Apple boards use EFI.
bare in mind the current motherboards are probably in excess of $500 if you could buy such a thing. Assuming Intel workstation pricing remains similar through the next few cycles it'll always make sense to sell and rebuy if you must have the latest technology.
Incorrect.
I plan on buying a Gigabyte P35 mobo that supports both DDR2 (4 slots, dual channel) and DDR3 (2 slots), up to 1333 mhz FSB. Price - $169 for retail kit with box and all the trimmings (8 SATA cables which will be especially useful)
DDR3 ram OTOH - will be about as pricey as FB-DIMMs are now. Considering I can get 4 gigs of DDR2 800 for around $180 (mushkin) - that's the route I'm going.
Assuming Stoakley-Seaburg comes out and is somehow the key to a next generation mac pro...
If I were to purchase a new mac pro this week... would i ultimately be able to upgrade the mother board when it comes out?
Macs are not upgradable. If you want to "upgrade" and tinker, buy a PeeCee. Sorry to be blunt, but that is the way it is. Upgrades are for cheapskates. Mac users throw the whole unit into the trash and buy a new one: that is convenience for you!
Honestly now... didn't we just have this discussion in some other thread? Let's not be sensational. Nobody is throwing out Mac Pros.
