Hi everyone. This is my first time posting so excuse me if I put this message on the wrong thread. I just recently bought an HP Pavilion p6714 desktop. It is mainly for school, but I was wondering if I could be able to run any games, mainly the Battlefield Series and the new game out in March Homefront. I don't have a lot of pc knowledge but I do know that my Geforce 6150 card aint gonna cut it. Can I run newer games with this PC if I just switch out the Geforce with a better one? Would I also have to get a new power supply to run the new card? Any help or suggestions would be very helpful. Thanks.
