Nvidia's GTX580 was my favourite video card for a very long time, and I have been equally impressed with its successor, the GTX680. We have already analysed several versions of the new design, but I can genuinely say that today we really do have something special for you. KFA2 have released two new overclocked, Limited Edition versions built around a stunning white PCB, with triple fan cooler. We have the more expensive version on test today with very limited availability, is it as good as it sounds? More importantly it is worth the staggering £559.99 inc vat asking price?

KFA2 are a relatively new name to the market and many people might not be immediately familiar with the branding. We reviewed a couple of their video cards recently, including the excellent GTX680 EX OC.

This 1268mhz boost version is available direct from Overclockers for £559.99 inc vat. This is only available in very limited quantities due to the low approval rate for such high clock speeds.

This card really is a work of art. The last time I can remember a white PCB was when Sapphire released their original PURE boards.

The KFA2 GeForce GTX 680 LTD OC has reviewed a huge core clock increase to over 1,200mhz, with an effective turbo boost speed to 1,268mhz. The GDDR5 memory is clocked at the same speed of 1,502mhz, or 6Gbps effective. We should notice some significant increases over the reference model, which is already lightning fast.

AMD have had it all their own way in 2012 as Nvidia have taken longer than expected to launch their latest ‘Kepler' hardware. The guys in green want to reclaim the high end performance throne with the ‘fastest, most efficient GPU ever built' and today we are looking at the latest high end GTX680 graphics card, courtesy of ASUS.

This review has been long overdue due to some hardware problems with previous GTX680 samples we received. When we finally received a fully working sample we had been forced to move onto other hardware in our ever expanding review queue. The life of a tech site is fast moving, schedules shift on a daily basis. But better late than never, we say.

By now most of you will have read multiple reviews on the high end hardware and we already know it is good. Nvidia always have one goal in mind and that is to win the battle, I do admire them for that.

Sometimes I can question the mental maturity of their PR and marketing division but on a hardware level they rarely disappoint. My only interest is the hardware they release anyway and that is why we are here today.

The GTX680 implements a new system of adjusting the clock speed and voltages dynamically. The goal is to ensure the ultimate performance level while optimising the power consumption. The interesting comparisons will be against AMD's HD7970 and MSI's overclocked R7970 Lightning and seeing how the new card slots into the overall market.
