I have a I7-2600 processor and 8gb of ram using windows 7 64 bit and occasionally my computer gets sluggish while browsing the internet. I also found that sometimes in one game I get pretty laggy when I have 25 mbps internet connection although usually only at night. I thought this might be do to many people on a server but sometimes i am the only person in the game experiencing this issue which makes me think maybe I need more ram. Any suggestions?
