1. I've overclocked my Ati radeon HD 4870 card to 790gpu clock and 1000 memory clock (maxed) but in catalyst control center on the same page as the overclock page, where it says "Current values" It still says the GPU clock is 500mhz and the Memory clock is 900mhz.

I'm not really sure why its saying its 500/900 when I overclocked it to 790/1000. Does it only take affect when its under load or something or is there something else wrong here?

Also I've ran the "test custom clocks" button on the same page and it passes the test everytime. So I'm still not sure why in "current values" it says 500/900 when I've overclocked it... Is it overclocked or isn't it?

2. The MOM.exe , "catalyst control monitoring program". What exactly does it do? I was thinking about terminating it in processes to free up some MB but I'm not sure if terminating the task will mess the video card up or not, not really sure what it's doing.

3. I'm sort of confused on how I should update the driver for my ati radeon HD 4870 card also...
The link for the driver is here

What is this legacy driver on the download page? Should I be downloading and install that or the regulare one, or both??? I'm so confused with this crap I don't understand why they don't do things more simplified.
