GTX 1070 i5 7600k or GTX 1060 and i7 7700k
I mainly play GTA V and I want to ask something for my new PC build.Is it much better in FPS if I go with an gtx 1070 and an i5 7600k or a i7 7700k and a gtx 1060 for 1080p gaming
7600k isn't a good investment, R5 1600 would be a better choice for a new system. GTX 1070 is a tad overkill for 1080p 60hz, if you have a 144hz monitor then by all means go for it.
The thing about benchmarks is that they run them on a computer with no software running in the background and no tasks running along side the game. A 7600K will do great with only the game running in pretty much all cases. But, then you start watching a twitch stream and that takes CPU power, you install an antivirus, you leave a few tabs of chrome open, whatever it is you'd do. All of a sudden, your performance dips in ways that you could have avoided if you had a couple extra threads to put those tasks on.
If you're doing 1080p 60hz, I'd probably do R5 1600 and GTX 1060 depending on the relative prices you can get them for, because it's not gonna be that long before you can get a card faster than the 1070 for $225. You can probably buy a 1060 now and a newer card faster than a 1070 in a year for approximately the same price as the 1070s are going for now and the 1060 is perfectly adequate to play 1080p60 during that time period.
