After nmp price/spec reveal i decide to keep my 8x2.93 for 1 year. (Wait for next gen haswell-e mac pro), so i want to upgrade my pro to match nmp in some area. especially USB3 SATA3 and GPU. Can you guys advice me? 1. SATA3 (As i found it's hard to find pci-e SSD that can booting os x) What card i can booting my mac pro? 2. USB 3.0, Can lacie kext use with 10.9. 3. Except 7950, GTX680 what card is safe bet to flash and get EFI boot screen. Thank guys. [UPDATE] Ok i can confirm your guys that PXHCD from 10.8 Kext can use with 10.9 but can't confirm it can reach USB 3.0 speed as i haven't USB3.0 device now.
