I have a 955 running at 3.8 ghz. I have had it for a while and to be honest I still feel like its really fast. I really dont NEED to upgrade but I have the upgrade itch again ( happens every 3-6 months). I have been beating my head trying to think of something to upgrade but I already am running an SSD i have 2 tb of storage running 12 gb of DDR3 , ( albeit 1666, guess i could go faster there) and 2 1gb 6870's in crossfire. Ive been looking at the FX4170 alot and I know with my board I could push it to 4.5 or faster on air with my monster heatsink but Im not sure I will see much of a difference and I wont get the upgrade itch scratched if it doesnt make some difference to me. Do you guys think I will see much of a difference with the fx4170 over what I have? Oh and yes I am a gamer. Please dont ask what type I dont discriminate.
