The X2 suffix has quite a lot of history with AMD cards. Anyone who remembers how amazing the HD4870X2 was will be eagerly anticipating the latest in the lineage, the HD6870X2. PowerColor are one of those companies that are well known amongst enthusiasts and their PCS+ and PCS++ line of cards have always produced outstanding performance. Now we have all the power of a HD6870 Crossfire setup, but on a single card. Billed as a GTX580 killer, we can't wait to see how it performs.
