Will a 0.7 ghz cpu overclock make a big fps difference in games?

So what your saying is, say, a .7ghz overclock on say, a bulldozer cpu wouldn't be as effective as a .7ghz overclock on an i5, or even a phenom ii cpu?
 
Also most games are not particularly bound by the CPU as long as it is not slow enough to bottleneck the graphic card. In Crysis 2 going from a stock i5-2500k to 4.5GHz results in an increase of 1 FPS. Skyrim on the other hand benefit a bit from an OC.

How much of a performance increase ultimately depends on the game. It's generally 0% to half the percentage increase of the overclock vs stock speed.

agreed i have 4 comps and amd x2 6400 be 3.2ghz with a gtx 580 and it will never get more then 20% gpu usage overclocking it to 4 ghzlet it use 5% more gpu power. about 5-10 fps in games i can even play. that are not cpu intesive

My Phenom 965 Be @3.4ghz uses 80-90% of the same gtx 580 giveing good fps in most games, 40+ on average overclocking it to 4.2 ghz gave me no noticeable fps boost.
My i7 950 @3ghz with game gpu give me full gpu useage and at 3.8 ghz gives me 1-3 fps on most games. never oc the gpu at that time.

My I5 3570kstock gives me 120%+ gpu usage with a good gpu overclock at 4.5ghz i see the same 1-3 fps added after the gpu overclock.

the i5 @ stock was always about 5+ fps higher fps then the i7 950 overclocked might have to do with hyper treading. that's with no gpu oc also or a light 800 mhz-27mhz oc.

Well I guess I'm really trying to decide whether I should get a phenom ii x6 1045T 2.7ghz or a phenom ii x4 965 3.4 ghz. Since most games only use 1-2 cores, the 965 would have the advantage because of its higher clock rate, but I'm wondering exactly how much of an advantage that would give. The main reason I don't get the 965 without a second thought is I will be doing heavy multitasking that I don't think it could handle. Probably playing a game while recording with fraps and rendering a video all at once. Oh yeah, I'll be using a 7850 and 8gb ddr3 1600 memory.

I just built a new rig to be able to play BF4

Corsair 650D case
Intel i7-4770K 3.5 OC'ed to 4.3
ASUS MAXIMUS VI FORMULA LGA 1150 Intel Z87
2 NVIDIA GTX 680 04g-p4-2686 (SLI) 4 gigs of mem
GSkill F3-2400C10D-16GTX CL 10-12-12-31 1.65V
Corsair H100i cpu water cooler
Corsair 1050 watt PSU
Intel 520 series 120 gb SSD
Kingston Hyper 120gb SSD
WB Velociraptor 70 gb HD 10,000 rpm
Seagate 2tb hybrid ssd/reg Hard drive
Sony DVD read/write 40 speed
Logitech YUY-95 illuminated keyboard
Corsair M-60 mouse
Razor Nostromo mini keyboard
Creative Labs 7.1 T7700 speaker system
Cyber Power 850 AVR voltage regulator and power backup
Three Dell 24" monitors
TYKE 73B - Triple Monitor Stand Free Standing Curved Arm
OS= Win 8.1 Pro 64 bit


I could not get a stress test to pass anything higher then 4.3 for about three weeks
and I spent hours and hours reading and looking for guides and trying everything, and
I finally did separate cores instead of syncing and now Im at 4.5

I was getting really disgusted and was thinking I had a bad luck of the draw
cpu, and then I was told that the difference between 4.3 and 4.8 in BF4
may have only made the difference in 4-6 FPS and it would not be
worth selling my CPU to someone who does not care about OC'ing
and buying one that was pre tested to 4.8

My temps in a stress test are at very high rates, 99 and 100 so I shut down
the test after 57 seconds, but while playing BF4, Im only at 58C tops
playing on three screens with two 580 GPU's and my FPS are about
77-88 with three screens and on a 120HZ monitor, I was getting
177 to 200 FPS while playing. I have all settings on Ultra for both
setups.

I dont know why I felt I had to get higher then 4.3, but now that I have done
it, it made me very happy after WEEKS of trying this and that.

Here are my settings during and after just playing the game.......

I have so much to learn and I know that tweaking will help me.

Thanks for the info on gaming.
