The ASUS ROG Swift PG278Q 27-in WQHD display with a 144 Hz refresh rate is truly an awesome monitor.

The PLS panel is definitely of better quality than the TN designs, even these slightly better than normal TN screens on the ROG Swift.

AMD R9 300-Series Possibly Coming Soon

by Scott Michaud |
The current rumors claim that Fiji XT will have 4096 graphics cores that are fed by a high-bandwidth, stacked memory architecture, which is supposedly rated at 640 GB/s (versus 224 GB/s of the GeForce GTX 980).
That said, they also have cache and other methods to reduce this dependency, but let's just say that, if you offer a graphics vendor a free, order-of-magnitude speed-up in memory bandwidth - you will have friend, and possibly one for life.
Starting with the CPU, at this point this is the first real attention POWER9 has received.
Relatively little information is available on the CPU, though IBM has previously mentioned that POWER9 is going to emphasize the use of accelerators (specialist hardware), which meshes well with what is being done for these supercomputers.
The X99 Killer series from ASRock is more of a gaming oriented lineup with features such as Killer LAN and LAG Free USB / PS2 ports.
To start off, the ASRock X99M Killer features the LGA 2011-3 socket supporting Intel’s upcoming line of Haswell-E high-end desktop processors which will be available to consumers along with the X99 chipset based motherboards on 29th August 2014.
