PowerColor has decided to give something extra to its customers by bundling S.T.A.L.K.E.R.: Clear Sky with its HD 4870 series cards.

The cards in question are PowerColor's water cooled LCS HD4870, the PCS+ HD 4870 and the plain non-reference cooled HD 4870. STALKER: Clear Sky is a prequel to the original STALKER: Shadow of Chernobil game, and is surely one of the better games that appeared in the previous year.

In addition to the STALKER bundle, PowerColor has also used the opportunity to launch a quiz contest that ends on March 31st with some cool prizes including three HD 4870 STALKER edition cards.
