from what you have posted your temps are very average and nothing to worry about...
if you have a stock cooler than your 2600k will probably max out at 65'c so getting a 3rd party cooler would be a good idea, as it will give a lot more headroom.
as for your gfx anything under 80 is fine for nvidia, gpus are designed to work at higher temps so as long as your at 50-79 then i wouldn't be worried. 1s you get 82-85 you know its time to clean out the dust and the temps will drop again. or if you can live with the noise turn the fans up by 10% this will knock 10-15 degrees off the max temp (use afterburner for this.(but remember to read up b4 you start adjustments))
but as i see it. your system temps are pretty much standard for stock cooling.
