Upgrading my PC to play games on a 1440 Ultrawide

[KoolKidKaos]

I need help to stop bottlenecking, not sure what CPU to get with a 1070ti, can anyone assist with this. Like the title says I do plan on getting a 34inch 3440x1440 Ultrawide, and I want to be able to play WoW, Overwatch, Skyrim, GTA V, and Tomb Raider on high settings and get a stable 55-60fps on it.


**CPU** | [Intel - Core i5-4670K 3.4GHz Quad-Core Processor]
**Motherboard** | [Gigabyte - GA-Z87X-D3H ATX LGA1150 Motherboard]
**Memory** | [G.Skill - Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory]
**Storage** | [Samsung - 840 EVO 120GB 2.5" Solid State Drive]
**Storage** | [Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive]
**Storage** | [Samsung - 850 EVO-Series 500GB 2.5" Solid State Drive]
**Storage** | [Western Digital - Caviar Black 4TB 3.5" 7200RPM Internal Hard Drive]
**Video Card** | [EVGA - GeForce GTX 1070 Ti 8GB FTW ULTRA SILENT GAMING Video Card]
**Case** | [NZXT - Phantom 410 (White) ATX Mid Tower Case]
**Power Supply** | [Rosewill - Hive 550W 80+ Bronze Certified Semi-Modular ATX Power Supply]
**Optical Drive** | [Samsung - SH-224DB/BEBE DVD/CD Writer]
**Operating System** | [Microsoft - Windows 10 64-bit]

I know I need a new CPU, MB, and Ram, but which CPU should I get

i5-8400
i5-8600K
i7-8700K?

Budget has no limit, but I do need it balanced around the 1070ti. Thanks

Will you be overclocking a K SKU?

at 3440x1440 resolution with a GTX 1070TI you'll be GPU limited in 99% of all games, so what CPU you choose doesn't ultimately make much difference.

I'd go with an R5 2600 or R7 2700 simply because more threads = better performance if you ever wanna stream gameplay or do "productivity" tasks.

I'd generally agree for that res and card match, but the few extra fps he gets from an oc'k intel k will make a difference in the games he's currently playing (they favour ipcxclock).
