I have a hp a6460t with Intel Core 2 Duo E4600 @ 2.4 GHz and 3 Gb of RAM. I am looking for a good card under 100 dollars to replace my horrible nvidia 8500 gt that cant run crap. Any suggestions? I know that the Nvidia gt 240 is good for the money, but will it be compatible with my system? (Mainly looking to play Starcraft 2) =) If its not, any other suggestions? Also, will 3 gb of RAM and my processor be sufficent for SC2?
