do not buy AMD/radeon. r9 known issue is a DIRECT X problem caused by the old rereales chips not having hardware support for the new DX changes and AMD will not be redoing the old 7900 series drivers for a fix. Took me weeks and lots of research and a couple of tech support dudes with loose lips tunes me in. DO NOT waste your time or money these chips appear only good on specs and real world results are unacceptable running new windows versions due to massive issues and returns of r9 series cards. The suppliers like gigabyte, asus are absolutly spewing at AMD and there is a lot of talk about some brands dropping thier AMD offerings due to brand damage cause by this AMD dash for cash releasing old chips they knew would not handle new DX changes and OS changes. SHOULD BE SOLD AS ORIGINAL CHIP and only as discontinued stock. DO NOT WASTE YOUR TIME RETURN ANY r9's and start again with the reliable Nvidia offerings.
