does anyone know if a CPU 8 pin power lead can be plugged into/suitable for a graphics card?
ive got a coolermaster realpower 650W (http://www.coolermaster.com/product.php?product_id=2551) and getting a radeon 6970 that requires 1x 6pin and 1x 8pin for power.

No, you can not plug the CPU 8 pin into a GPU 8pin, as they are phased differently, and the leads are in a different pattern. Sure, you could physically plug it in, but you will have a nice paperweight ;)

Yeah, just get an adapter, also I know some GPU's actually come with an adapter from Molex to 8pin.

^You confuse me there Tricksta, the way that reads you're saying some eight pins have a four pin?
or am I reading it wrong?
Op, your graphics card may have adaptors bundled with it, either check online or wait till you have it before ordering one,

Sorry moto.

What i meant you usually have a 8 or 6pin molex adapter and even if it doesent come one you can get one for about £4

It is not a case of phasing but polarity. The two connectors are wired differently. Plugging either one into the wrong connector (you are not supposed to be able to do this) will result in shorting 12 volts to ground.

If you are lucky, the PSU will detect this and electronically shut itself down. If you are unlucky, you can fry the motherboard, graphics card, PSU, or possibly the CPU.
