I am considering both the retina and non-retina 15" MBPs for video editing with Premiere CS6 and Final Cut Pro 7 (and occasionally FCPX) and had some questions. How much of a performance hit will the retina display cost the system in comparison to the non-retina display version when editing and processing large video files (e.g. 1080P ProRes HQ)? I assume it must affect real time playback capability but to what extent? Would it also affect render times or is rendering all handled by the processor rather than the graphics card? When the retina MBP is running in pixel-doubling lower resolutions, would this actually free up the graphics card to the level of if it was running a lower resolution screen, or would there still be more load on the graphics card as it is still having to refresh so many pixels (even if four for every one pixel are the same)? I understand Photoshop CS6 is being updated for retina displays. Does anyone know if Premiere Pro CS6 and the rest of the suite will receive a similar upgrade and if so, when? Also, regarding the Thunderbolt to FW800 adapter - does anyone know if this will carry power from the TB port so that bus-powered FW800 drives can still be powered off it? Also, do the two thunderbolt ports share the same bus, or could I run two FW800 adapters at the same time and get good throughput from one FW800 drive to another on the other port? Regarding the built in SDXC card reader - what are the transfer speeds? - will it read at faster speeds than a USB2 (or even USB3) SDXC card reader? I need to transfer large video files via this port so it would be a great benefit if performance is better than an external reader - USB2 is definitely too slow! Also, is this on the same bus as the Thunderbolt ports (I ask because if on a separate bus, I could presumably get faster data throughput when copying SDXC cards to a portable hard drive connected via thunderbolt)? Also, would I be able to plug a FW400 to FW800 adapter into the FW800 to Thunderbolt adapter to read from FW400 drives? Would I be able to digitise via this rather unwieldy setup from a DV camcorder? Would FCP7 (for example) still recognise this as a FW400 connection? I appreciate that the machine is so new that a lot of these questions will be difficult to answer so soon... Thanks for any help though!
