I'm trying to get setup to edit 4k video, I am running the current system: Processor: 1 x Intel® Core™ i7-4790K Processor (4x 4.0GHz/8MB L3 Cache) - Intel® Core™ i7-4790K Memory: just upgraded to 32Gb of DDR3 Ripjaw Video Card: 1 x NVIDIA GeForce GTX 980ti - 6GB - Single Card Motherboard: ASUS Z97-K -- 2x PCIe x16, 4x USB 3.0, 2x USB 2.0 Primary Hard Drive: 1 x 120GB Kingston V300 SSD + 2TB 7200RPM HARD DRIVE (Videos are on 2TB Hard Drive) Operating System: Microsoft Windows 7 Professional + Office Starter 2010 (Includes basic versions of Word and Excel) - 64-bit When playing 4k video (from a GoPro)in a player like VLC it plays smoothly, when brought into an editing environment like Premiere it slows down and stutters after a few seconds. I just added 16Gb of RAM which made zero difference. I am using the Mercury GPU Acceleration Memory Playback Engine. I don't get it 4 x 4.0 GHZ i7 + 6GB GPU + 32 GB of RAM one would think = 4k video editing. Any help would be greatly appreciated.
