Increasing FPS

When you write I nice juicy reply to find out it bugged and didnt send >.> Short summary is that you probably only need a new CPU. Graphics arent used much in an old game like gmod. Your CPU needs a high clock speed. Not high core count. Gmod is too old to use more than 2 cores very well. so if possible a dual core 5ghz cpu would rock gmod! Or atleast thats what I figured out via friends an my experiences. Id suggest getting a 4 core cpu with 4ghz or more. 4 core so you can play other games and multitask.
