Is better to go with XFX RX 6080XT than EVGA RTX 3080? Since I have Ryzen


i just brought a AMD Ryzen 9 3900X ... and a 2070 S....

would the 4000 series be much better than the 3900x?

This excellent AMD Ryzen 9 3900X price is an essential upgrade for your gaming PC's CPU

If push came to shove, looking at cheap gaming CPU deals can often be a frustrating experience, as all the best performing processors aren't really, well, cheap. And while this deal here isn't ridiculous, for what you get, we think it really does represent a cheap gaming CPU deal. Right now, you can get the AMD Ryzen 9 3900X - the AMD CPU that sits the highest on our list of chips that are the best CPU for gaming - for (basically) it's lowest ever price right now in the US

Have a GTX 1080, Ryzen 9 3900x, and a 2k ultrawide monitor but had to drop it down to 2560x1080 and high settings to attain a good framerate, but loving the game after 5 hours and have had very minimal bugs.

Indeed! I upgraded from a i5-7600K to a Ryzen 9 3900X. You don't know what speed is until you go AMD!


AMD Ryzen 9 3900X Review

And as a core-crunching power chip, the Ryzen 9 3900X is without peer on value for money here in mid-2019.
