I don't know if this will help but it might! I bought my mac book pro in late 2009! It's specs are as listed:
OS X v.10.6.7
2.8GHZ Intel Core 2 Duo
4GB 1067 MHz DDR3 Dual Channel Ram
Nvidia GeForce 9600M GT 512MB VRAM
I got it when it first came out! It retailed for 5,000 USD! Luckily i was in college at the time and got it at the Student Discount Price of 3,000 USD! My Family Flipped out when i brought it home and told them how much I had spent on it! At present it still runs as good as that day i bought it! My Family now begs me to let them use it!
I personally was wondering if it would be a good purchase on the day I bought it! Now I am sure it was!
I hope that helps with your decision!
