otherwise, if you find something better, how good are your soldering skills?
...and no, Apple won't do it for you!
If you wan't to play the best games on your MBP...... it will be upto you installing windows via bootcamp, or VMware.... and the amount of Ram you have.
Macs aren't gaming computers, but many install window's via bootcamp, or run VMware just for their gaming needs, and have no complaints.
A step further would be waiting for the next gen of MBPs, and the processors and graphics chips/cards that come with.
