I'm mainly gaming on my system.
However as the GTX 980's struggle atm to max out 4k displays let alone double or triple 4k displays, I REALLY hope Nvidia (and AMD although Ill never buy the red teams cards again) have something up their sleeves for CES 15. Mainly if they released a slightly more powerful GTX 980 with say 8GB of VRAM each (for a total of 3 8GB cards in SLI) , that would be pretty much exactly what I'd be looking for.....not holding my breath, but then we may see some games being maxed at at least 4K. Also we need to see G-Sync be pushed to multi screen setups with higher refreshes and hopefully higher bandwidth display port.
Lastly DDR4 prices need to come down soon
Not saying ANY of the above will happen at CES 15 but I really hoping for at least some this Jan.
