Would I see a decent performance boost going from an i5 6600k to Ryzen 2700x. I've been struggling in games like BFV and AC Orgins with the i5 6600k paired with an RTX 2070. A lot of stuttering and lag spikes even on medium and high settings at 3440x1440. Would it be enough to mitigate those issues, going to the 2700x or should I look at other CPUs?
Nah! go for intel man it way much better if ur only using for gaming tell me ur specs u see the 2600x outperform the 2700 not the x version due to their L3 chach iam telling that go for the the intel i7 or i5 the k version u will get an impresive results
Price and performance-wise, 2700x is good choice to go for 2070. However if you are willing to spend a few more bucks for a intel side of things it will serve you way more better than 2700x. You can go for i7-9700k for about $200 more.
It's a unbeatable pair of performance.
In the games you mentioned you should see a moderate improvement because they will utilities more than 4 threads very well. I’d expect higher minimum FPS and average FPS but you might see lower maximum FPS. Your current cpu actually have better single core performance before being overclocked, it just lacks total core/thread count.
On games that only use 4 threads or less you will be downgrading performance due to Ryzen’s lower single core performance.
I’d wait for Ryzen 3 before choosing. Some reports are claiming a big boost in single core performance allowing it to match Intel.
