PC upgrade advice: i5-3470 and GTX1070

[marlu15]

Hi all, I'm in the process of upgrading my components and would like to know if my CPU will (significantly) bottleneck my system when trying to run modern games on a 1440p/144Hz monitor: (Rise of the Tomb Raider/XCOM 2).

Specs:
CPU: i5 3470 3.2Ghz (3.6Ghz boost clock)
RAM: G Skill Ripjaws X 16GB (4x4GB DDR3 @ 1600Mhz)
PSU: Silverstone Strider 500W ST50F-ES
GPU: EVGA GTX 1070 SC (Being shipped)
MOBO: MSI H77MA-G43
SSD/HDD: Samsung 840 EVO 250GB/WD Blue 1TB
Case: Silverstone Precision PS08 Micro ATX case

I'm upgrading from a 600Ti and recently bought an Acer XB270HU monitor to work with my old 1080p @60Hz monitor in a multiple monitor setup. I only plan to game on the Acer monitor.

I'm definitely upgrading my case to the Corsair Obsidian CC750D and am considering changing the PSU to a modular designed one at a higher wattage.

Any advice would be greatly appreciated, Thanks!

You're less likely to have a CPU bottleneck at 2k vs. 1080p, at 2k is when the GPU becomes the bottleneck again.

Gamersnexus.net shows about half of the games at 1080p on an OC'd intel 8 core w/HT had similar performance on a 1070 vs. 1080 because of CPU bottleneck, but at 2k the two GPU separated themselves again in performance because at 2k the GPU became the bottleneck again. You're not even getting the 1080 so you're even less likely to be CPU bottleneck at 2k.

That's a relief since replacing the RAM/CPU/mobo seems like a waste at this point in time. Hopefully I can hold onto those components for another three years. Thanks again.
