I assume the hard drive is still easy to upgrade in the MBP? If so, buy an SSD and stick it in your MBP and you'll be even more amazed at the speed.
yeah, I replaced the HDD in my old MBP with no issues (very straightforward process as long as you have the proper screwdrivers), so that'll probably be my next performance upgrade once I've got another $300-400 sitting around. first upgrade, though? a 2x4GB Mushkin RAM upgrade
I'm confused...
Are you trying to say instead of encoding one movie at 27x on your old CPU, you're encoding two movies on your new CPU at 29x?
ie. Are you saying the Sandy Bridge CPU is roughly twice as fast at video encoding than the old C2D?
well, I'm actually batch encoding my lossless music library to a lossy format for use with my car's stereo, but I assume it'd be the same case if I was encoding a movie... the process has been running for a little over 2hrs, and the range has dropped to the 25-28x I'm used to, but that's still more than impressive considering this is still a dual-core CPU with only an additional 300MHz of "oomph."
