We've been waiting since December for Apple to announce the mythical 12-core MacPro's so we can purchase one for video post production use. I've been editing on my MacBook Pro laptop since then and today was the final day of waiting for us. We're trying to get the "best bang for the buck". We edit HD video (XDCAM EX, ProRes 422, Uncompressed HD, green-screen, big AfterEffects renders, etc...) We have invested in some very fast mini-SAS RAID's for external storage, so now we just have to figure out what CPU to buy. CPU CHOICES 2 x 2.26GHz 2 x 2.66Ghz (+$1400) 2 x 2.93 GHz (+$2600) The other decision is what to do for a fast, reliable boot drive so the system and applications will launch fast. BOOT DRIVE CHOICES Single standard hard drive (7200 rpm) Dual hard drives striped together as a RAID-0 (Apple tech told me that this configuration is faster than a single SSD drive) Single SSD (need a way to mount a 2.5 into a 3.5 slot) We're set on buying 12 GB or RAM based on BareFeets testing that shows that 6-slots of RAM is faster than 8-slots. (weird but whatever) And we're set on buying the ATI Radeon HD 4870 512MB graphics card to run our 30-inch Cinema display and 24-inch LED display. Any advice? We're going to place our order tomorrow morning. Thanks in advance!
