Does the cpu actually effect gaming that much? I want to get the i7 3770k soon. I will be playing games at the maximum settings at 1080p. I will also be getting a gtx 670. How much will the cpu effect the games? Will I still be fine with a i7 3570k? I want to be playing at 50 fps+. I will be overclocking.
That i7 shouldnt have a problem with anything really. Many games dont use much CPU power to run. There are, however, some games that will use more CPU and bottleneck your graphics. In your case though, the 3770 wont bottleneck the 670, and you should be able to run pretty much anything at 50 FPS in 1080p.
If all you want is reasonably playable rates like 60FPS, most games are GPU-bound at high resolutions and will hit 60FPS on almost any modern CPU with stock clock. Even the "ancient" Core2Duo E8400 (3GHz) can still pull 60-80FPS in many modern games if given a good enough GPU for the resolution and details.
Overclocking on top-end CPUs is only required if you want to try breaking benchmark records or need the processing power for something else.
A phenom II at 4.0 +Ghz, or a Nehelem based quad core at 3.7+ Ghz will run pretty much anything there out there today. Any stock sandy bridge based quad core will do the same. There are a few games out there that will take more if throw at them (BF3) but even these will run fine on these cpus.
i7 processers doesnt performs well as i5 processers in gaming the i7 processers does performs better in photoshop and other applications.go for i5 save some money put it on good cooler such as cm 212+ evo and overclock it get more performance in gaming.
btw its good processer for gaming without oc also but its k series one which means way better overclocking chips like amd be chips the k series overclcoks very well whenever you feel like you are getting some low performance overclock it and be happy.
What kind of games are you playing? MMO's generally take more CPU and GPU. I've been told that the 2500k will only get 35-45 FPS even when paired with a 680 on Guild Wars 2. Keep in mind though there was a bug in the beta that made the gpu almost useless and ran pretty much solely on CPU. And there were 100s of people on the screen.
