The bro’s over at vr-zone state that April 6th is gonna be a big day for AMD as they are going to launch a slew of new cards. As we have told you back in February, Radeon HD 4890 (RV790) is slated for April release and the confirmed date is now 6th of April. Interestingly, we also heard RV740 is pulled in from May to early April release so AMD will probably launch the new cards on the same day. Link
