Rather than bundling its products with free game vouchers, Palit chose to let its GeForce GTX 650 Ti sell under their own power.
To make them stand apart from the others, the company designed them with custom PCBs (printed circuit boards) shorter than the reference one
The 1 GB and 2 GB GTX 650 Ti adapters work at the normal speeds (928 MHz for the GPU and 5,400 MHz for the GDDR5 VRAM memory), but the Palit GTX 650 Ti OC Edition moves a bit faster (1,006 MHz for the GPU and 5,500 MHz for the memory).
Sadly, Palit didn't say what price its cards sport. Fortunately, we can guess: the normal 1 GB card has no reason to sell for more than the original ($149 /149 Euro), while the other two will ship for a bit extra (the 2 GB is probably the most expensive, despite the lack of factory overclocking).
