So i tried to play on my older bro's com which had a core 2 duo e7200 2.53ghz, a gt 605, relatively new hard drives and he couldnt even play csgo at the lowest settings(he gets like 15fps), so i pitied him and also treated myself to a MSI 960 twin frozr and i gave my 750ti twin frozr to him. But his ancient cpu is bottlenecking the gpu so much he now plays csgo at 35fps at lowest settings... it even gets to like 20fps when shooting. When i had the 750ti, i got around 200fps on max for csgo, will changing the cpu into like a Q6600 quad help? The reason why i didnt change his whole motherboard, ram and cpu is because im only 13??? and im not rich so i found a $25 q6600 and i was just wondering if it will help. Skype takes up 40% of his cpu usage???.
