Now might be a good time to upgrade your gaming PC's display if your current model is feeling old in the tooth. Two of ASUS' gaming monitors are on sale from now until December 30th at 3:05AM Eastern, and both of them pack features you might appreciate. The ROG Swift PG279QZ has dropped to $450 from its usual $599, making it a considerably sweeter deal. The 27-inch, 1440p screen packs a 165Hz refresh rate (with NVIDIA G Sync support) as well as an IPS panel, giving you very smooth gaming and IPS' vivid colors. There's also eye fatigue reduction for those marathon Modern Warfare sessions.
