XFX lose the fastest-clocked GTX 512 competition, though. EVGA submitted a final engineering sample of their e-GeForce 7800 GTX BlackPearl 512MB a few days ago. Clocked out-of-the-box at 600/900, the watercooled graphics board also challenges for the title of world's most expensive consumer VGA board, tipping the money scales at a scary $1000. We shudder to think of the converted UK price, fully expecting it to be in the high £600 range, closing in rapidly on £700.

For the money you get the board and all the watercooling hardware - from radiator to reservoir and tubing inbetween - required to run the card at 600/900 in 24/7 safety. Indeed, the sample provided was validated to run at 612/905 using the standard air cooler, so some of the appeal switches to getting those clocks in silence, as the watercooling affords you.
