In a bit of a quandary here and need some practical advice from the experts! I had an old MP 2008 (8 core 2.8) that I used for some simple editing in FCP and quite a lot of transcoding in Compressor, MPEG Streamclip and Sorenson Squeeze. Not super fast, but fast enough to crunch the video files I was giving it. I sold the MP last week and now all I have left is my Core 2 Duo 2.8 MBP to perform the above duties (I was going to fit an SSD and fill the RAM to give it some extra oomph) I wanted to replace the MP with an Ivy Bridge iMac, with USB 3 for my growing storage needs and the right CPU would probably equal or exceed the number crunching potential. But they don't arrive until maybe October. With the iMac doing the heavy lifting, I no longer need the 15" MBP. So was thinking to swap the 15" for the 13". So do I swap the MBP now or later? Will I see an improvement on the above tasks with the slowest 13" MBP? Budget is always constrained, having sold the MP for a decent wedge and still having the MBP + 23" monitor still to sell, I am hoping I come out almost even. Thank you for your indulgence.
