I am happy with configuration as i did improve the ram to 8 GB....Apple does not seem to have any form of upgrade service....and when you call them they through you about, make you call different places.....I just wanted to find out about improving graphics as i use aperture and photoshop and also bootcamp with windows 7 for gaming....I just wanted some information. I know the GPU is on the motherboard i would just be interested in upgrading that..
It's not possible to upgrade the GPU on your MBP.
You will need to upgrade to a new 2011 MBP, but first check out the benchmarks for the applications you are using as GPU dependent apps may not show much of an improvement from 2010 to 2011.
Have a look at barefeats for benchmarks.
The performance bottleneck for your MBP is the hard drive.
You will see significant improvements in overal performance by upgrading the HD to a SSD.
Btw, Apple is not in the business of upgrading your existing MBP. Apple rather you buy a new MacBook Pro.
In all fairness to Apple, the 2011 MBP quad-core is almost twice as fast as the 2010 MBP dual-core for multi-core aware applications.
Here are Mac benchmarks.
