Does the 512MB ram help when using 3d modeling programs? Does it help when an external monitor? I game on my desktop PC, so, I don't care about the game performance.
With the cpu, I know the 100MHz difference is pretty much negligible, but what about the 6MB cache with the 2.5GHz?
I still doubt the $2499 MBP is worth it, but sometimes, I do irrational things...![]()

The 512 VRAM helps sell the laptop to people who have no clue about GPUs. A Penryn CPU should run faster and more energy efficiently.

All but the most powerful GPUs top out at needing 256MB. Only the top few cards would ever use more than 256MB, so you don't need to pay extra for 512MB as it is essentially worthless.
Which 2.4GHz processor? Which 2.5GHz processor? Penryn should run better yes, but only under specific circumstances would the $100 be worth it (and I'm guessing it would not be worth it for you). -
You'll notice the 100mhz boost way more than the cache, and you probably wont ever notice the 100mhz.
That is assuming you're not doing huge number crunching, cause you're buying a laptop. -
256 is perfect for a laptop graphics card.

people always get caught up in the cache. the clock increase matters more, and, as stated, you most likely won't even notice that.
lets put it this way, anandtech did a series of benchmarks and found a 4.8% avg improvement of the 2.5ghz penryn over the 2.4 ghz penryn, (6 megs vs 3 megs of cache) However, the clock speed is 4.167% faster in the 2.5ghz model over the 2.4. I'll leave it up to you to decide how important the extra cache is. -
Yeah I'm surprised people are getting hung up on the 1mb cache. I'm not sure people are comparing the correct model cpu.
The 2.4 is a replacement for the old 2.2
2.5 replaces the 2.4 etc.
So you'll see a small but welcome bump in processor speed. I doubt unless you were encoding all the time you'd notice the difference though. Each Intel bump is a small step.
I've just bought heavily discounted 2.6 Merom 17" which has about the same grunt as a new 2.5.
FSB is still a major bottleneck. We should see a bigger step up when Montevina appears with 800/1066 FSB's
the VRAM and the cache...
