About Nvidia’s GTX 660 GK106:

The core’s overclocked performance in comparison with the non-reference @ stock setting is not impressive. One would be curious about the performance difference between the reference and non-reference to see if there is any significant boost.

There’s also the issue of games getting locked if I go more than 1117MHz on GPU and/or 1542 MHz on the memory clock. The card’s core ability to give nice overclock performance results is restricted. The card uses 6-pin power on the non-reference card, and one may suspect if this got to do with Power limiter that Nvidia has on this by default. I’ve read GTX 660Ti gives better tweaks and performance difference even on reference editions are pretty good.

The performance is pretty decent only with 1680 x 1050 (and possibly 1080p resolution) with low/medium preset and high in certain games. But the beauty of the ability to overclock a PC hardware for gaming and therefore get better performance is stifled.

About Asus’ card:

Asus has a good card but with a mediocre GPU. Not that I am saying GTX 660 it’s a bad product, it’s just that the part where certain games/benchmarks get locked after raising GPU Core and memory clock to a level. If the performance difference between a reference and non-reference on the stock is also insignificant, you need to ask: Why make a non-reference for such GPUs if the performance and overclocked performance in comparison with stock is disappointing?

There is something peculiar about the fans on auto. Even when idle and on stock the fan tends to spin up (the noise is audible once you push it 69% fan speed) at certain intervals. I am not sure if this is something that Asus has embedded on, but it didn’t happen on HD7850 and 650Ti- both Direct CUII Editions.

The non-reference cooler is appreciated provided the manufacturer makes a better-than-reference card overall. It keeps the card cool- with ALLHD benchmark on 1440 preset (cat Zilla), it stayed 70 degrees on load with an ambient of around 25 degrees Celsius on an open test setup.

I’ve read ABOUT GTX 660Ti card and it does overclock nicely. Even the reference versions do a better job and give better overclocks- and also, you can go for tri/Quad SLI setup with 660Ti whereas 660 is restricted with dual card setup. You may want to look into that and/or see what the red team has.
