I am planning to build a ryzen 3000 series PC to max out dota 2 at 1440p 144hz. Any recommendation on what is the best spec to maintain the FPS at 145 with ultra graphic setting?

Kindly share your specs and FPS

Hmm, currently I am using LG Ultra Wide monitor with 75hz and freesync, after I played dota with my Razer Balde with 144hz screen and I did feels the different. That's the reason I intend to upgrade my current Monitor.

Others than dota I would play some games like Battlefield/World of Tank as well, might not able to fully utilize the 144hz refresh rate but it still make differences while you scroll you mice at the dekstop xD.

Btw thanks for your advice, decided go for 5700xt and it seems favorable at 1440p.
