2.4 vs 2.5 macbook pro ?

[proenca]

Hi there,
I'm torn between two macintosh'es -
I have an option of buying a 17" Macbook Pro with 2.4 ghz ( 3mb cache on cpu ) AND with the high def display ( 1900x1200 ) , 256mb video memory
or a 17" Macbook Pro with 2.5 ghz ( 6mb cache cpu ) with "normal" 1680x1024 display, 512mb video memory

I will mainly use it as a processing workhorse ( i want a laptop again, Im using a iMac 2.0ghz for that now that I-m selling to a friend ) but I dont know which to choose ( im buying refurb )

I process in Lightroom 90% of the stuff, sometimes some PS3 but very rarely. Both macs come with 4GB ram, and Im concerned that the 2.4 model has "only" 3mb on cpu cache - the bigger plus is the HD display for working on it.
I guess that video memory ( I dont do games honestly ) is secondary here ?
I process only M8 DNG's files.

Ideas ?

ps > 15" no go, I prefer a 17" . 🙂

The 2,5 has a 512MB graphics card witch its twice as big than the 2,4.
Also the front bus speed off the processor is twice as fast. Power consumption is less making the battery last about 50 minutes longer 🙂
Max out the RAM witch is nowarday's reasonable prices with from Apple.

Do you really need the 17" ?? are you editing in the field?
The 17" is a big laptop making it a pain to travel with. If not you are better off with a seperate 20" or 23" monitor using the duals screen function. Witch makes work much easier than with a single larger screen 🙂
