Yeah, we tried rivatuner and the control panel, even tried to do it in the computer restart menu.
But it never let us do anything 
well both rivatuner and the control panel work for me as far as overclocking. although my card seems to glitch out after a little bit on the furmark stability test. it also adds little to no FPS increase by overclocking, anyway. No more OC'ing for me heh. :-/
if you get no increase in performance by OC'ing your video card, that means your CPU is bottlenecking(holding back your GPU's performance) in your system
I've got a 2.3ghz phenom x4.. figured that'd be powerful enough...
I did see an increase in FPS, but it was no more than 3-5fps.. nothing major and IMO, not worth the over clock.
Cpu is too slow 
At least get it over 3ghz if your going to overclock your GPU that much!!
@RenoBlade : The only thing you really have to worry about is if your motherboard supports SLI or Crossfire and if you care about getting two cards in the future. Otherwise buy which ever graphic card is the best in your price range and DX11 if possible.
And what I mean by shock, is your never have to play games at 20< FPS, and belive me games completly change when they are at 60+ compaired to 20. It's like playing a different game, and that's ignoring the graphical detail increase.
hehe i see
but as you told donik before, it seems my cpu is bottleneck atm.
as the 2.2ghz dualcore is even worse than his 2.3 x4 (quad core, i guess? )
well. i need to get my money sorted before i decide what to get. i think i should get a new board with cpu aswell as a grafic card and new joystick for mwll, if theres nothing else i need to get first 
i7 will run faster than a duel core, but not becuase it has 4 cores, but becuase the structure of the CPU is better. This is just becuase Crysis/MWLL only really uses two cores half decently, any more it doesn't do anything, game performance wise.
However, other games and applications that you may use, will use that quad core far better than a duel core, if they are optimized for it. A game I always like to use in this example is GTA which is far far better with a quad. Oh and quads are better future proofing yourself
If you just overclocked your CPU nearer the 3ghz mark, you would gain a pretty steep performance wise in anything that needs the CPU, and in games it would still be the bottleneck, but it wouldn't effect the FPS to a standard it is at the moment. 2.6ghz is about as low as I would go, and even that you would notice the difference. Small increase at lower speeds, makes a far bigger performance increase than at higher speeds. So 2ghz to 2.2ghz is far bigger increase than 3ghz to 3.2ghz.
There are alot of people running MWLL on CPU clocked under 3ghz, but they are normally around 2.6ghz and are still able to get high or max settings with a good graphic card. Of course if you have a mega powerful GC, it's helpful to have a CPU over 3ghz to really take full advantage of it, no matter how good your GC is, if your CPU can't cope, your not gonna be able to run the game as well as you should.
