Will I need more than 4 GHz on CPU for gaming?
Will I need more than 4 GHz on i7 9.. series for gaming?
here is my rig: Intel i7 930 OC to 4 GHz, GTX 580, PSU Antec 1200 W, 3x SSD Intel X25-M 80 GB raid 0, Evga X58 SLI motherboard, CORSAIR DOMINATOR GT 6GB 1600 7-7-7-20
i wanna play games like Crisis 2, Metro 2033, battlefield bad company 3... i saw on other forums that people saying that more than 4GHz CPU does not effect on games. is that true? it's effects only when you running SLI.
IMHO 4ghz is ample if not, then maybe overkill. Most games arnt really cpu heavy, only a handfull are. Crysis 2- uses a lot less cpu usage than the first because most physic have been taken away completly to optimise performance for the console port (check out the tech demo..then compare to how the released version looks). BF3 will use suprising not a hole bunch of cpu usage, as that just how they develop their games, they optimise by lowering physics but over compensating small details like partical effects, shaders etc. As for Metro there physics are instense so rather than using CPU use an Nvidia card with physx and take a huge amount of stress of the CPU. ATM im playing crysis 2 with DX11 Ultra on about 30-40FPS, BFBC2 40-60FPS, Metro 25 - 35FPS with physx, all this with a 2.6ghz CPU. As treefrom07 said "You are more likely to be limited by your GPU than CPU." So Yes a better CPU will get better results but a better GPU will give you better again.
Unfortunately, it is not true. If you want to game at 1080p settings (1920x1080) or higher with the highest detail settings, then you will have to overclock. You can certainly game at lower resolutions or detail settings, but I like my games to look good, so lower settings are unacceptable. I just bought this system in January, and I'm already regretting that I didn't get a mainboard that can do SLI because in some games I need the extra power. I can't get any higher on the CPU, or I would.
Every extra MHz you can get out of your CPU is more power for supporting the graphics card you have.
2500K @ 4.8GHz
GTX 570 @ 830 core, 2100 memory
here is an example, my 930 NOT overclock
my 930 OC

This made me remember : The higher your resolution, the higher your CPU overclock should be. For example, if you have 3 1080p monitors, you'll need more CPU power.
But for a single 1080p monitor (a non-3D one) you should be okay at 4GHz. You wouldn't see a difference if you went to 4.2 or 4.4.
However, if you someday decide to add a monitor, switch to 3D or add a second/third video card, then I'd try 4.2GHz, even 4.4 (if you do 3D vision surround with multiple video cards, for example).
Have fun !
