If they OC that high, that saves you about $300. So at least my calculation was right. Most MoBos out there have 8xSATA 3GBit/s, so 2 more than the MP. A 4 port SATA 3GBit/s RAID card is however $100, not $699 as Apple wants us to believe - let alone SAS, InfiniBand and FibreChannel. 80% of the users just want simple SATA 3/6Bit/s hardware RAID0/1/5. For the rest 20% suites the $699 card.Get i7-930 and overclock it to ~3.5GHz. That you cannot do with Mac Pro. Add decent CPU cooler and it will be dead silent and cool. With a PC mobo you have more choices, e.g. more SATA ports, PCI/PCIe slots etc
The only Mac which needs ECC RAM is the Big Mac. However I was rather refering to DDR3-2000 and such stuff, however MP's EFI may set them to DDR3-1333 or DDR3-1600.You need Xeon in order to use ECC RAM although most people are fine with non-ECC
Again, I diff'd against the i7-970. I calculated the same $150 for the C2Q, but people more likely use $40 socket 775 (or even $30 if equipped with DDR2) motherboards than $200 1366 ones, which makes the whole system cheaper.Core 2 Quads aren't really cheaper, they start from 150$ in NewEgg (2.5GHz). You can build iX rig for about the same $. There is no reason to get other than the low-end i7 because you can overclock it. If you bought used parts, C2Q would end up being cheaper but iX is still worth it. A quick calculation shows me that i7 930/860 rig would cost around 1000$, depending on the components you get
Again, $550 i7-970 vs. 300$ Phenom II X6 1050T. Overclocked to 3.5GHz it's - at least - comparable, because it has 6 full-functional cores rather then 4 real ones and 4 HTT'ed ones. Also, regarding to the performance, the X6 identifies itself as HT capable and benefits from HT enhanced code.Phenom II x6s aren't that great. In fact, i7s beat them in most benches as they have Hyper-Threading. I wouldn't get AMD Hack as the support is worse (they have different chipsets) and I have no idea how AMDs perform under OS X
I had a Athlon64 3400+ (2.4GHz) Hackintosh with Leopard, and it performed A) faster then on Windows 7 and B) as fast as on Linux, so at least these run pretty full-speed on Mac OS X, even with emulated SSE3. I don't think this would be much different with the Phenom II's.
The 7xx chipsets ran fine last time I checked, however I don't know about new 8xx series. The drivers are basically copied from FreeBSD, so you could say they are fully supported. Mac OS X = Darwin = BSD, so there is not that much work to fully port such things. Rewriting the drivers from scratch is not needed and there wouldn't even be much Hackintoshes out there, if people had to. It's just changing it's interface from being baked inside the monolithic FreeBSD kernel to being a kext and talk to the XNU.
