I recently purchased Serious Sam II and found out my video card (NVIDIA GeForce MX420) will not run the game. :blackeye: I would like to upgrade to the best model of NIVIDA card that will work on my computer and is cost effective. I am using an HP Pavilion 734n, athlon, AM37 motherboard. I have looked at all of their models, but can't figure out which one is best for my situation. I am not planning to do further upgrades to this computer other than the video card.
