Overbuild quality or no, you can get a non reference 780ti which is faster in every sense except 4k gaming (which if you have a 4k monitor price isn't an issue anyhow) for around 100$ less. There is virtually no reason to buy this over a nVidia card....and I'm and ATI fanboy
I've wanted a 290X since release but, between the heat issues and all the crypto mining causing the prices to skyrocket I can't find a single reason to pick one up.
