Just increase the core clock in 10MHz steps and test each time with something like 3DMark11 or Heaven benchmarks, if you get visual artifacts or driver crashes then you have gone too far for the current voltage.
You can either back it off 10MHz and leave it there or you can increase the voltage a notch and re-test, continue doing this till you get the desired clock speed, bear in mind increasing the voltage will increase the temp so you will have to monitor these while benchmarking and also gaming for the first few times.
Looks like the VID on your card is 1.051v so the next notch is 1.064 then 1.076, for everyday use i would't go past 1.1v really especially on a stock air cooled card.
Once you get the core clock where you want it (850MHz is a decent everyday overclock) then u can work on the memory in the same way whilst leaving the core at the desired overclock, u won't get anywhere near the same performance gains overclocking the memory as you will the core but it's worth upping a little (should be able to get 2025MHz easy enough and more than likely 2050MHz).
Edit: Also wow is quite a CPU dependant game so i have heard so i would look at overclocking that i7 950 to around 4GHz if u haven't already (specs in your post show 3.07 GHz @ 2.79 GHz which is underclocked from stock unless it's a typo).

Not to change the subject but 8GB DDR3 on x58?

Regarding the ram X58 runs triple channel and u have a dual channel kit, ideally u want 3x2Gb or 3x4Gb kits to fill all the grey dimm slots, and yes i would look at overclocking the cpu first, should be able to get 4GHz easy enough.

To be honest, I think you're fine running everything at stock. WoW isn't that hard to run. What resolution are you gonna be recording at?

Haven't OC'd a 920/950 before, but ran across this OC thread awhile back.  May be of some use for you.  More detailed answers would have to come for a former/current x58 user (sorry).
 
Generally though, and this applies for any type of OC you do (CPU or GPU - and even RAM) - take it in small increments and test after each.  Personally, for CPU OC's, I like to use LinX as it is faster than Prime95 to test for basic stability.  Once I have my OC to where I want it, I'll then run it through Prime95 to test for more long term stability. 
 
EDIT:  Oh - I should also mention...you may want to post the specific question about the CPU OC in the 5 Series thread.  You'll probably get more people looking at the post that can help you.

For CPU - I prefer LinX and Prime95.  LinX for the "quick" check of stability (typically takes about 10 minutes or so to run).  Prime95 for the longer stability check (I usually let it run for around 12 hours - but some will let it run for a full 24). 
 
For GPU - I like the Heaven benchmark program or the OC Scanner from EVGA.  I use Heaven because I think it's pretty cool.  The OC Scanner gives you a little more flexibility to shut it down if it finds any issues so you don't over heat your cards. 

As for the RAM - generally yes, it is possible to OC your RAM.  However, OC'ing your RAM may require you to tweak your CPU OC.

I OC mine 580 1.5GB on SC Clocks, voltage is default 1025.
New GPU-Z totally confused me because  wrong Pixel Fillrare.
GPU-Z 0.5.0 show right for Fermi. My idle temps is about 45C.
But because it's hot summer now.
 
I  have profil and in games is always under 80C.
That's OK for stock card.
 
 

Hey boballee
 
 Thanks man for all the information you really helped me put my self in the right direction. For the next few days I am going to study and do research on how to OC this i7 950 and try to get it as high as possible (not to the extreme though ;)).
 
While I am doing that I should be able to purchase this aftermarket VGA cooler for my 580 gtx, I have been hearing a-lot of good things for the ARCTIC Accelero Hybrid Extreme VGA Cooler-nVidia/AMD, Liquid/Air Combo Ultimate Cooling. 
 
I don't stress my cards that much either but I will be doing some high quality renders with Autodesk programs for a few animations. The OC should be able to help make things go smoother and better especially with the new SSD card on the way. 

Thanks Maniacvvv
 
Ill be sure to take a look and see what you got there. I appreciate the help!

Happy to help.  Maniac's guide linked is really good.  That should get you all set up on the GPU OC.  I have several OC's set up on my 580's (afterburner gives you up to 5 settings).  I have my stock settings, a mid-range/everyday overclock and then an 'extreme' overclock that I use for benching. 
 
Good luck and just be careful - it can be both very frustrating and very addictive!
