Question about PSU and video card for new build.

First off, what wattage PSU do I need for an i7 950 and GTX560 video card with one hard drive.

Also, will that video card do 1920 x 1080 @120hz? I remember old video cards spec sheets use to show what max resolution and refresh rates they could do, but not anymore. They just show the max res so I'm not sure.

Thanks.

refresh rate has ceased to be an issue in most cases thatd be why..

a gtx 560ti overclcoked will do what you want in any case if the refrence clocks dont do it for ya

anyway id probably say your fine with 500 watts +

Nvidia recommend 500watts so that should be enough, a little extra headroom such as a 550 or 600watt won't be bad.

Thanks for the info, so the CPU doesn't really matter when choosing a PSU, it's all about the video card(s)

Will the 560ti only do it if it's overclocked or will the stock one do it? I'm looking at this one below, it's the TI but not sure if it's overclocked or if that's something you do on your own.

The reason I ask is because I have a certain windows program I need to run at 120hz.
