I have a socket 1150 system but I want to get a 32" 4K monitor that's on sale at Costco. If I upgrade to a better GPU will that be sufficient with my 4770k & 8GB ram? Or is the Z87 chipset system not adequate enough? Currently I'm gaming on a 2560x1440 monitor with a GTX 780. I have no intentions on building a new system. Thanks. Oh also, what's the new standard for 4k gaming now? HDMI 2.0?
