Questions about build?
4870 QE support is already inside OSX because Apple sells the card......
Hi all, I've read this entire thread with great interest and I've decided to try a hackintosh.

My MBP died recently, and I need a low-cost replacement for now.
My questions are:
Will a 2 GB 4870 card work and/or be of any benefit? I'm planning on going Sapphire since it seems to be the card of preference.
Someone claimed that the 2.66 GHz. quad core i7 has better overclock potential than the 2.8 GHz. Why is that if the 2.8 binned higher? At any rate I'd be more than satisfied with a mild overclock in the 3.2 GHz. to 3.6 GHz. range. My planned cooler is in the list below, I'd appreciate any feedback.
Which of the Gigabyte motherboards is the hot pick right now? I was thinking the X58A-UD5, I'm mainly after a totally boring Kakewalk install.
Here's my proposed gear list:
Intel Core i7-930 Bloomfield 2.8GHz LGA 1366 130W Quad-Core Desktop Processor
XIGMATEK Intel Core i7 compatible Dark Knight-S1283V 120mm Long Life Bearing CPU Cooler
Arctic Silver 5 Thermal Compound
GIGABYTE GA-X58A-UD5 LGA 1366
Sapphire Technology ATI Radeon HD 4870 1 GB
OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Seagate Barracuda 7200.12 ST3750528AS 750GB 7200 RPM SATA 3.0Gb/s
LG 22X DVD Burner - Bulk Black SATA Model GH22LS50 LightScribe Support
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V
ABS Canyon 595 Black Anodized Aluminum Super Full Tower Computer Case
Any red flags? Thanks for taking a look!
