I have a self assembled system with 16gb ram, an AMD Phenom II X6 (6 core @ 3.2hz not overclocked, yet) on an MSI NF980-G65 mb, currently running a GTX770. The system masters everything at 1080p with graphics maxed. Playing stuff like Dying Light, Mad Max, Borderlands/2, Doom, Fallout4, Far Cry 3/4, Crysis 3, Path of Exile and that sort of thing and it's completely fluid. I upgraded my AVR, lost the analog inputs for PC, had to upgrade to a Samsung 55" 4k tv so that HDMI would work right, and now that I have a 4k TV my vid card is having trouble keeping up during PC gaming. I started a cascade of events. Gaming at 4k ads a whole new level of pain to an older video card/processor. I can still run games at 1080p but it doesnt look as sharp going from 46" to 55" so I figure I'll need to update the system to handle full 4k. I know the GTX1080 is the card to have but I'm not sure how it's going to work without the full CPU upgrade as well. I thought about an AMD 8370/Asus 990 R2.0 pro. but I think the Zen chips are just around the corner and from what I'm reading they might be Intel killers. I'm wondering if keeping my current setup but adding the GTX1080 adn maybe OC the CPU some would get me into 4k territory or if I might be bottlenecked by the older processor to the point that 4k gaming would not be a reasonable expectation. I'm sure I might have to dumb down some settings until I do get the full upgrade and thats ok. I'm planning to upgrade the processor/mb but would like to wait for the Zen chips to come out and drop in price. I might add that for an old AMD 6 core it's really zippy. Should I get the GTX1080, would it be worth it or should I just wait until I'm ready to do a full upgrade. Opinions, experiences? Any input from PC gamers that have been down this road? Thanks.
