Performance wise, you're getting a card that is more than capable of providing an excellent experience at 1080p and 1440p, while moving up to 4K we saw 60FPS+ in most of our games (which we run at Medium/High settings).

That said, having a high-performing reference card will probably make the initial benchmarks look extra impressive, which could be a win in itself.

SAPPHIRE fans will be jumping at the Tri-X R9 390X 8GB, and with two of these in CrossFire, you're in for a huge amount of fun.

AMD R9 390X Is Rumored Liquid Cooled

That said, having a high-performing reference card will probably make the initial benchmarks look extra impressive, which could be a win in itself.
Personally, I would hope that a standalone air-cooled model would be available.

Intel Broadwell Architecture Preview: A Glimpse into Core M

by Ryan Smith |
www.anandtech.com
When it comes to building and configuring Core M, Intel likes to refer to their efforts as the “Fanless Challenge,” reflecting the fact that their biggest goal with Core M is to comfortably get the processor in to 10” tablets under 10mm in thickness that are passively cooled.
The end result no doubt limited what performance optimizations Intel could integrate into Broadwell’s design, but it also functionally reduces power requirements for any given performance level, furthering Intel’s goals in getting Core performance in a mobile device.
