I have a Samsung laptop with Intel core i5 processor, 4gb ram and a nvidia geforce gt 330M graphics card. I was wondering if i could upgrade my laptops graphics card to a nvidia GeForce GT 650M 2gb. can i do this? if i can but not that size, can you recommend the best one i can get?

99% of the time you cannot upgrade your laptop GPU, laptops are not made to be updated (a part maybe ram and hard drives) There is a lot to be considered, the GPU's would be insanly expensive and even the extra heat generated from a superior card could be a issue, in short i also do not recommend you OPEN your laptop if you dont know exaclty what you are doing, there are a lot of things easy to brake or permantly damage. If you look up on youtube you can find how to open a laptop, incase you ever want to clean the fans, etc. You can take a look and understand why nothing can be changed.
