Like the look of AMD's Radeon HD 7800-series cards but want Pitcairn with a serving of Gigabyte's excellent WindForce cooler? Then you're in luck, as the Taiwanese manufacturer's custom-cooled variants of both the HD 7870 and HD 7850 will be available in time for launch on March 19.

Up first, the HD 7870 OC (model number GV-R787OC-2GD) will carry the same WindForce 3X cooler that adorns the company's HD 7970 OC and features a Pitcairn XT GPU gently bumped up from 1,000MHz to 1,100MHz. The 10 per cent bump in core frequency is handy, but the card's 2GB frame buffer will continue to run at a stock 4,800MHz.

AMD's Pitcairn Pro, meanwhile, gets a garish makeover in the form of the HD 7850 OC (model number GV-R785OC-2GD). This one features a WindForce 2X cooler and a GPU factory overclocked from a default 860MHz to a meatier 975MHz. Memory, once again, will tick along at an effective 4,800MHz.

Gigabyte's still assessing pricing for both cards, but we can expect to see the HD 7870 OC and HD 7850 OC in stores on March 19.

Those are actually pretty nice core overclocks for retail cards. I never really saw the point in buying an ‘OC’ version when they only increased the core by 15MHz or so, like in the case of Gigabyte's HD 6870 OC.

Why no memory overclocks, though? Are they cautious of stepping on the toes of other cards in the series? The Hexus review of the HD 78xx cards shows they'll both run a 1GHz overclock on memory at stock voltages, so I guess it just comes down to marketing.
They might not have found memory clock increase to be particularly useful. Review sites always ramp up the memory speed but in my own experience it doesn't help too much.
