Hi, i don't really know much about computers but I am looking to upgrade my video card, the one i currently have is a NVIDIA GeForce GT 540M, which in my opinion sucks... I mainly play MMo's and this is a lap top i play on, I have a Dell XPS L502X with a Intel Core i7-2720qm cpu @2.20GHz with 8gb's of RAM. I feel like m y video card is really holding me back and would greatly appreciate any input on what i can do or if i can even upgrade my video card. If anyone can help me out on finding what i exactly need or steer me in the right direction it would be greatly appreciated.
