It looks to me like there's a duplicate between the Asus Radeon R9 280x suggested by pickandchoose and the Asus R9-280x Direct CU II suggested by pavl. Besides the MSRPs, I can't tell any difference - the first mentions Direct CU II in the description. If it is a duplicate, this is having a potentially significant role in the votes and should be fixed, and voters notified if they voted for both.
The MSRP on the lower-ranked card is also the correct MSRP, and it's $70 less. The 289x is meant to compete with $300 cards, not $400 cards like the GTX 770. My reference is http://m.hardocp.com/article/2013/10/07/asus_r9_280x_directcu_ii_top_video_card_review/#.Ut9uKTnnaMk
nukeThe R9 290x and R9 280x are 2 very different cards. The R9 290x is AMD's current top of the range gaming card, the current fastest mining card and one of the first to support Mantle technology. The R9 280x on the other hand, is a rebadged 7970 1Ghz with a price drop, not that it's a bad thing though, as it's awesome value for money. Direct CU II is basically the type of cooler the manufacturer puts on it. Gigabyte call their's windforce, MSI calls theirs TwinFrorz etc In car terms, it would be like MB C63 AMG and E63 AMG. Both by the same company, and labeled similarly, but are very different cars.
ChaosMasterOops - I copied the info from the wrong card into my comment. I meant not the R9 290x by John, but the Asus R9 280X Direct CU II by pavl. It looks like this R9 280X by pavl and the R9 280X by pickandchoose are duplicates. I've edited my original comment to reflect this. Thanks for avoiding name-calling and giving me the benefit of the doubt.
