It is sad, but these days Leadtek mostly sells copies of reference graphics cards, sometimes with different coolers they also buy from third parties. But we hope this is only a temporary setback and the days of customization are not over for the company.

Today we shall review as many as four graphics cards and try to find out whether Leadtek has actually added anything to those, except labels and boxes.

Specifications

Like we expected, GTX 570/580 are copies of the reference design. The GTX 560 Ti card was made by Leadtek, but feature a minimum of changes and the reference cooler. The GTX 550 Ti card is actually more or less customized, with improved power circuitry, more compact dimensions and a custom cooler.

Maximum resolutions and frequencies:

• 240 Hz maximum refresh rate
• 2560 x 1600 @ 60Hz max. digital (DVI) resolution
• 2048 x 1536 @ 85Hz max. analog (VGA) resolution

All cards require supplementary power: GTX 570/560 Ti have two 6-pin sockets each, GTX 580 has one 8-pin and one 6-pin socket, and GTX 550 Ti has one 6-pin socket.
