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

get card equivalent with rtx2070 super... sometimes, it wount stay 145... sure +/- few fps .. dota 2 can play 144hz? its not even first person shooter... i dont see any different play 144hz or 75hz with same resolution.

then buy what monitor to pair with this spec?

mainly for gaming? other than dota? lol... get something worth to spend... like freesync(for amd card) or gsync(for nvdia card) now nvdia card support freesync too.. but need upgrade driver and patch... if u intend buy 1440p resolution monitor.. get 27" or 32".. above than that.. 4k...

If
Fhd 24inch?

fhd 24" is more than good enuf for dota..

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.

I got try fps 120hz before
Dota in 144hz what's the experience from 60hz

5700XT

Just wondering, can integrated graphics like intel uhd 620 able to play dota 2 at high settings?
