Well I have this HP pavilion that I really want to upgrade, I want to start doing some gaming on it but I don't want to spend that much because I feel like I won't even keep this computer for that long anyway. Gpu: Integrated Nvidia GeForce 6150SE Psu : 300 watts Ram : 3gb ddr2 Mobo : M2N68-LA (Narra3) My model number is: A6430f I know that I should probably upgrade the Psu first but I can't buy both the Gpu and Psu at the moment. If I were to upgrade my Gpu would that be able to run on this computer? I probably will just end up, upgrading my PC anyways but I would like to know. Thank you.
