Hi there...

Auto select should be okay but sometimes you might need to select your GPU, i once had a problem with GTA IV that wasn't using my gpu for physicX and the game started lagging. I don't know if it was a problem with the drivers or not but selecting the gpu for physicx manually solved the problem.
Normally physicX should always be on your GPU as the type of operations it processes are always related to physics effects with uses high amounts of floating points data types and cpu are not optimized to work with those type of data, only our gpus dues to their number of processors.

What do you mean by a green tint... green pixels? if so those are artifacts and it means your graphics card is overheating... check your temps while playing

im quite sure its not overheat,it looks different to artifacts,its like putting on green sunglasses,the green tint comes over the screen,it sometimes happens when im just playin MW3 and the temps are fine,its strange

A greenish hue? Yes... that is strange...
Try going to nvidia control panel and then select (adjust desktop color settings)... then select a different color format, i only have rgb and ycbcr44, so i'd try the second one, maybe you can also try selecting "use nvidia options" where you can calibrate contrast, hue, saturation etc... but i am not sure if it will override games settings, but it's worth a try...

The colour returning to normal when the card cools down would suggest a broken card rather than a dodgy cable, I assume you have no spare VGA cables about or one you can borrow?

the video card is a month old,almost brand new,i need to buy a VGA cable coz i dont have a spare one,i will try that first,the highest temp i have seen is around 80c when playin BF3,i think that is not enough to kill the card,is that right...thanks for the assistance

Both of my 560's hover around the 80c mark when folding and can get there whilst gaming as well and I've had these cards since April.
