How much FPS improvement will I get?

[iFaymous]

I am thinking about overclocking my AMD Phenom II x6 1055T 2.8GHz to somewhere around 3.4-3.6GHz. Here is the FPS I am getting right now on some games.

BF3 Ultra 1366*768 - 50 in CPU Demanding Open Map Areas (Caspian Border)
Skyrim Ultra 1366*768 - 45 in CPU Demanding Cities (Whiterun and such)

I can get 60+ frames everywhere else except CPU Demanding areas. But the question is, how much would that improve my framerates?

from pure math, 3.4/2.8=1.21. So at best 21% faster cpu.

If this is a complete linear application then your 50fps then turns into 60fps.
which is your best case scenario that you can hope for if you are completely CPU bound.

Realistically though, if you are actually GPU bound then you get 0% increase as shown in this article.

Why don't you try it and find out.

If you have the capability to OC your chip, it is well worth it, however, keep in mind if you are GPU bound, you may not see much performance boost.

In BF3 multiplayer, the overclocking will help. In Skyrim, it will have an effect also. Go for it.

Another thing is, I need to buy a new motherboard and CPU fan to overclock, costing around $130. Its that worth the price of performance?

 

[obsama1]

Just get the fan.

What is your current motherboard?

What is your current motherboard?

I have a prebuilt computer so the mobo is default and won't let me overclock which kinda sucks.

 

[mocchan]

Ahhh, so that's the reason why you mentioned a new motherboard. I would definitely recommend it if you have no plans to upgrade/build a new rig in the future. It would benefit you greatly in terms of performance even with as light OC.

On a prebuilt, Windows is tied to the mobo, so if you replace that, you'll need a new copy of Windows.

here is an idea, download amd overdrive and use it to test an over clock. if it gets you the results you are looking for then get the motherboard, if not then you might save the money for a more extensive upgrade

i bought a cheap emachines 5 years ago and have upgraded my motherboard twice since then. neither time have i had an issue with windows

 

[obsama1]

That's unusual. Because HP and Dell use OEM copies, so a new motherboard means a new copy of Windows. Didn't know that though.

I cant even overclock with that lol. I have tried and I can only downclock.

 

[humphreybot]

did you try amd Fusion too?

 

[mocchan]

By AMD Fusion I'm assuming you mean APU's and the like...I don't see how that would tie in with what OP is looking for IMO.
