the 2.53ghz mbp was the model that came out in late 2008 and then they updated it to 2.66ghz a few months later and that is the one you are talking about with the "fresher parts". I bought my 2.4ghz mbp when it first came out end of last year and have had no problems with the graphics card at all. If you just bought it though I think you should have gotten the 2.66ghz. Check apples website to be sure though.

so the only difference between the late 2008 and the 09 is the 2.66ghz?
 
Return it!

You should for sure return it.

1. the newer model is compatible with up to 8 gigs of DDR3 ram. This might not make a difference right now, but in 2 years when you are looking to upgrade this will make a huge difference.
2. iLife '09 includes updated software like iPhoto with facial recognition
3. You bought a new laptop they should give you a new laptop
 
That's weird. If you purchased a Apple product today, it should've been the "refreshed" models and not the original late-2008 model. Everything you got in-box is correct except for the processor. I would definitely go back and get the latest model, not the original.
 
You bought a new MacBook Pro within the previous 2 weeks? If this is the case, you should have gotten the 2.66 GHz model, since that's the current model going out. The 2.53 GHz were when the new unibody design was just introduced.

So, in that sense, you should go back and ask for an exchange, unless otherwise they explicitly stated to you they were giving you an 2.53 GHz model and you accepted and now don't recall.
 
Slight problems -

1) Battery capacity = 4600. Lower than my old white macbook. Was this updated in the '09/"refreshed" macbooks?
2) If I install iLife 09 on a computer than had iLife '08, will it be the same thing as if I bought one with it preinstalled or will it take up more space?
3) I've heard that there have been some problems with NVIDIA with these unibody mbp. How do I know if I have such problem?
4) Coconut battery said that I had 3 battery loadcycles when I had only used it for a day. Is this normal?
5) I did notice that when the screen is lit all the way and the screen is black - for example, I used Front Row the other day and noticed when the screen was dark but lit up that towards the bottom there were some small lighter circles. Are these supposed to be there? They're not too noticeable.

And finally - is there a big difference other than the processor between the late '08 and '09 versions?
Just take it back and get the new one. If you purchased it new recently, it should be the 2.66 model with the better internals, end of story.
