Sapphire Toxic HD 4890 Vapor-X

A 1ghz core clock GPU?? Insane and unbelievable if you ask me, but that’s what Sapphire’s 4890 card is all about (with a teeny little OC touch). Defaulting with a monstrous 960mhz core using the 4890 core (RV790), what we have here is a card that rivals even the GTX 285 in some games, while trading blows with its current competitor, the GTX 275.
