stick with the standard, no sense in spending the extra 10 bucks just for the VERY slight overclock.

overclock the thing yourself
make an account on EVGA and download the new software they put out called EVGA Precision. you can overclock it as well as watch your temps and adjust the fan speed to your liking kinda like rivatuner but EVGA style
*edit* and if your worried about heat issues, pick up an Artic Cooling Accelero S1 with a 120MM fan, dropped my stock cooler temps for my GT from 80C down to 39C under full load and playing crysis for a few hours
