Direct CUII TOP versions usually have a similar illustration on the box. They could work on putting 1-2 add-ons though.


The sample came with (I think) pretty much everything compared to a retail pack- except the card was gift wrapped using bubble wraps. I wouldn’t be surprised if you get the anti static bag by default. You get a DVI-to-VGA converter so it should be used if anyone requires them for any reason.


It would be nice if non-reference versions were bundled with a game just like in the old days. Also, unlike GTX 650 Ti Direct CU II that I’ve reviewed before, the packaging of this GTX 660 variant doesn’t use Polyethylene Foam protection, rather cardboard box is used to the card in place. But you are getting the driver utility with GPU Tweak software.


The non-reference GTX 660 comes with the GPU core clocked at 1072 MHz and 1527 MHz respectively.

GeForce GTX 660 (Reference) ASUS GTX 660-DC2T-2GD5
Shader Units 960 960
ROPs 24 24
Graphics Processor GK106 GK106
Transistors 2540M 2540M
Memory Size 2048 MB 2048 MB
Memory Bus Width 192 bit 192 bit
Core Clock 980 MHz 1072 MHz
Memory Clock 1502 MHz 1527 MHz

The key difference in specs is the core clock and memory clock. Rest of it on paper is the same.
