Hey ladies!
For anyone being interested in knowing the performance and power-usage difference of the various CPUs here is a link to a benchmark that tested various Intel Mobil CPUs in the very same laptop system.

According to another thread on the MR forum the new MBP 2.53 use a T9400 (35W) instead of a P9500 (25W). While this means higher power-usage it seems that according to the linked benchmarks the T9400 also delivers better multi-threading performance, while the P9500 seems better optimized for single-threading.
Because of that for me personally the T models are better suited for my heavily multi-threaded professional audio applications.
I'm still out on wether I will chose a 2.53 or 2.80 MBP or prefer a "military build" HP 8530w with its better screen-resolution. There are no demo models at any of the nearby Apple dealers yet, so I will have to wait a bit before I can try them hands on.
