PowerColor Radeon HD 7770 1GB

PowerColor's Radeon HD 7770 1GB card is a pretty accurate clone of the reference card. The cooler's casing diverges slightly, with vents in different places. Frequencies mirror the reference's 1,000MHz core and 4,500MHz memory, however.

A single CrossFireX finger enables a second card to be connected for multi-GPU trickery. Performance is reckoned to scale by almost double in triple-A games, according to AMD, but our own research, albeit with Radeon HD 7950s, has shown otherwise.

Four screens can be connected from the PowerColor card. The firm includes a mini-DP-to-DP adapter in the box, though, still, DisplayPort-equipped monitors tend to have a large premium over HDMI/DVI screens. A better adapter would be one that converts one of the mini-DPs into DVI, enabling easier three-screen usage, but including one is sure to markedly increase the cost of the bundle for this basic HD 7770. We're informed that this model - AX770 1GBD5-2DH - is to retail for £125.
