Products from Leadtek frequently visit our test labs and always show good if not best overclockability, largely because of their inventive cooling systems. The Leadtek WinFast A400 Ultra TDH was even originally overclocked to 425/1100MHz (instead of 400/1100MHz), but the frequencies were brought down to the default in the next versions of the device’s BIOS (for details, please, see our article called Leadtek WinFast A400 Ultra TDH Graphics Card Review ).
The PCI Express version of the GeForce 6800 Ultra is still rather scarce in shops. The ATI RADEON X850 XT is much easier to find, but now that the GeForce 7800 GTX has been released, these graphics cards have lost much of their appeal.
The GeForce 6800 GT, on the contrary, is a widespread device, and some samples of this card can work at the frequencies of the GeForce 6800 Ultra, thus making a good graphics card for a PC enthusiast who’s into NVIDIA’s solutions. Heat dissipation of the NV4x core quite naturally grows up at overclocking, so the overclocked card must be equipped with an efficient cooling system, capable of handling the increased thermal load. The standard single-slot cooler many GeForce 6800 GT come with isn’t the best choice in this case.
Of course, you can purchase a good cooler separately, but it means spending more money. So, if you do buy a GeForce 6800 GT with overclocking in mind, consider models originally equipped with high-performance coolers. One such card is going to be reviewed in this article.
It is Leadtek’s WinFast PX6800 GT TDH.
