I've had the new 2.53Ghz MBP since day 1 (err.. 2 days go!), and there's no comparison in terms of speed. Games run MILES better. I can play The Witcher pretty much maxed out etc. This is in comparison to my old 2.4Ghz Penryn MBP. Also, if you use LightRoom2, you're in for a REAL treat. Finally I can use the brush tool without ANY lag at all. It's unbelievably fast in that regard. How come benchmarks aren't showing this? My apps start faster, my apps RUN faster. And yes, this is in comparison to a FRESHLY installed 2.4Ghz Penryn system with 4GB DDR-2. Anyway, for those on the fence, jump over to new MBP!
