I was kind of hoping that the X80 and X80ti would have HBM2, but who knows, they could change the specs later.
It's a pretty good deal for the price, I've had a good experience with Dell keyboards in the past, but lately, the quality has been declining.
if you're really lucky, you can grab a gtx 670 on ebay for $80.
I've had a good experience with Asus boards in the past, If they are too expensive, Supermicro is definitely a good alternative/
Let me just say, ebay is always your friend. If you're lucky, you can land a pretty good deal.
I have a gtx 980 in my main rig right now, and looking back, I really should have gotten the 390x. It is much cheaper, while faster than the gtx...
