hey all i currently have the phenom x4 9950 cpu at stock clocks. bf3 and skyrim and gta4 choke this thing. i know my board ( biostar ta 790gx 128m) can only support this cpu. due to some power plane or something. but this is the best it can hold. how much better is the 945 than the 9950? tigerdirect has it for 100 dollars. is it worth it?
