Question Phenom II x3 720 is bottlenecking my 1070 GTX.

Oct 11, 2019
Howdy! The gist of things is that I'm getting real low FPS in Total War Warhammer, and I've been slowly upgrading components over time. Basically, my GPU died awhile back, so I bought a new one. Upgraded from a HDD to a SSD, which was AMAZING. Awhile later my monitor died, and could no longer be resuscitated, so got a new one of those. And now my 'classic' CPU is bottlenecking the GPU. And has been for two or three years. My system does fine in GPU-intensive games, but terribly in CPU-intensive tasks.

Current system:
AMD Phenom II X3 720
Asus M4A79T Deluxe -- PCIe 2.0
MSI GTX 1070 Gaming X
8 Gigs of RAM
1440p 144hz IPS monitor
Seasonic M12D 850W PSU

Approximate Purchase Date: Either this month or the Black Friday sales.

Budget Range: $500-600

System Usage from Most to Least Important: Gaming, watching videos/movies, moderate video editing

Are you buying a monitor: No

Parts to Upgrade: CPU, Mobo w/o Wi-Fi, RAM, probably aftermarket quiet CPU cooler, quiet PSU

Do you need to buy OS: No

Preferred Website(s) for Parts: none

Location: Middle of Nowhere, California, USA

Parts Preferences: Ryzen 3600 probably

Overclocking: No

SLI or Crossfire: No

Your Monitor Resolution: 1440p 144hz IPS monitor

Additional Comments: I CANNOT have Wi-Fi, appreciate a 'good value,' hate RGB lighting, and crave silence. ATM my PSU is the loudest thing in my case, just whirring away off and on. It's lasted a decade, so I can't complain too much. :p I've sort of landed on the Ryzen 3600 as the value/performance sweet spot, but after spending several days going down the motherboard & PSU rabbit hole I feel like I know less than I did when I started researching. I'd appreciate your advice on what motherboard to put a potential Ryzen 3600 into, as well as whether I should get 16 GB or 32 GB of ram. As for the PSU, again, good value & quiet. I mostly just play games & do light to moderate CPU-intensive work. I've noticed that on Youtube I can only reliably watch videos at 480p; I can only do 720p if I'm not doing much else. Conceptually, I'd like to explore watching things at 2K or maybe even this mystical 4K that is now A Thing.

And Most Importantly, Why Are You Upgrading: single-digit to mid-twenties FPS in TW:Warhammer, similarly low framerates in other CPU-intensive applications; CPU bottlenecking GPU & monitor
