I wanted to pipe in to say the same thing. For the longest time, I thought my Late 2008 15" MBP couldn't handle 8GB (chipset issue, I though). I figured 6GB was the largest, and I just stayed with the 4GB as it came from the factory. Then one day late last year, I realized that a) the Late 2008 15" MBP can take 8GB and b) 8GB of RAM was now VERY affordable.

It made a huge difference. No more constant thrashing of the HDD as it tries to manage a large swap file.

And here's a link with some evidence for 8GB in that MacBook Pro, for posterity: http://blog.macsales.com/9102-secret-firmware-lets-late-08-m...
