I have recently bought a refurbished MacBook Pro with OSX Lion 10.7. It has a 2.3 Ghz Intel Core i5 processor with 4 GB of memory and an Intel HD Graphics 3000 card.. All of these stats are really good except for the graphics. I know the graphics card is built into the motherboard, so how much would it generally cost to upgrade my graphics card to something like an nvidia or AMD Radeon? I'm trying to figure out how but it seems to me that I am going to need somebody who really knows what they are doing to help. Thanks for the help!

Hate to be the bearer of bad news but there’s no way to upgrade the graphics card on a Macbook pro. It is permanently embedded onto the logic board so the only way would be to change out the entire logic board (a process that would be extremely expensive). While there are sites that would suggest it possible, I strongly advise against it. To attempt to break and re-solder the connectors which are only fibers wide would surely damage the board beyond repair.
