Bump..

any more test results? I am thinking of getting a 560 Ti and am definitely interested in this thread.

I bought a MSI Twin FrozR 560Ti last week, it's a 1GB version and runs CoD very nicely indeed, will post some benchies tomorrow hopefully.

I'm tossing up whether to get a 1 or 2gb 560ti card for CoD. Would like to go the 2gb version but they seem to be in very short supply where I live. Still haven't seem anything definitive that the 2gb cards offer better performance over the 1gb versions...

Depends on the resolution, at 1680x1050 and below 1GB is enough, above you need more ram.
If you play at something like 1280x720 buy the 1GB version, at 1680x1050 you are at the limit.

In reply to vram testing, Rivatuner don't recognize the latest Nvidia driver I'm using so I cant test, and don't know of another vram monitoring tool that I would trust.

Also

After the patches arrived things got amazingly good with "Medium" settings across the board grass, roads etc on, FPS Avg up in the 70-80's online with v1.00.14072

Not yet tested "High/Very high" yet though :)

EVGA Precision, is build around rivatuner and support the latest driver

Yes bit no Vram monitoring

Only overclocking crap :)

Maybe it's the PSU?
 

Check if the noise is coming from your Power Supply, as sometimes when a power hungry component such as a CPU or graphics card switches to a heavy load, such as when your flying, it can cause a noise to emanate from the PSU. If so it could be a transformer humming due to heavy load, or a fan that is increasing speed. This is more likely to occur if your computer is near the maximum wattage of your PSU, or if your PSU is slightly aged, as the capacitors and such age within it lowering the max wattage slowly over time.

Got one of these babies ordered along with aother 4GB of Ram , looking forward too it.

Alpha, IIRC with Precision you can hit the spanner icon and set it to monitor memory usage on the onscreen graph (you might have to clk graph with mouse and scroll down to see it, or you could untick everything else so only it shows), though dont think you can save a log but it should give you a good idea of where you stand.
