The Leadtek WinFast GTX 260 Extreme+ (Leadtek Limited) performed above average thanks to the factory-overclocked core running at 602MHz, and once overclocked further provided the best mid-range card performance. Temperature was no problem here, and the cooler operated quietly. There was no shortage of peripherals and should be ready out of the box for almost all end users. Based on the 55nm core, this card definitely saw benefit as the efficiency was increase and nearly brought the card to GTX 280 levels.
