I am currently using a Zotac 1070Ti in my mini-itx build and would like to upgrade, I play games at 1440p and have an Acer ET322QU with the following specs.
31.5" IPS panel
2560 x 1440 WQHD Resolution
AMD Radeon FreeSync Technology
VGA, HDMI, DisplayPort Inputs
Built in Speakers
Blue Light Shield and Flicker-less Technology
PIP/PBP for multi-tasking
4 ms Response Time
My system has a Ryzen 5 2600X and a B350 motherboard with 16GB DDR4
Thats a great question, I am not sure as I am currently using my monitor with an Nvidia card and it seems to be working well with that, not sure if I need a Freesync GPU.
Frankly I wouldn’t bother upgrading for 1440p. Your options:
2070S = US$499, Smallish upgrade, ~25-30%
2080S = US$799, we don’t know for sure as still embargoed but probably a 40-45% upgrade
2080ti = US$1199, ~60% upgrade
There are no current AMD GPUs that are an upgrade from a 1070ti. Vega and Radeon 7 are EOL and the 5700XT is a sidegrade.
Well the 2070S will give you roughly that level of performance but it won’t be a big upgrade.
1070ti = basically a 1080 minus a bit
2070 = basically a 1080
2070S = basically a 2080 minus a bit
1080ti = 1080 + ~30%
2080 = basically a 1080ti
2080S = probably a 2080 plus a bit
Locked vsync is the best possible experience, but you would need to maintain 144 fps at all times, even in the middle of the largest battles, for that to be the right path. Typically you can only guarantee that in old games or lower refresh rates. I doubt a 2080ti could lock 144 fps at 1440p in many modern games.
Why do you feel you need to upgrade? A goal would help us better answer. 1070ti should be adequite for your setup so do you have a goal in mind? i see that the monitor is 75 hz, so maybe a slight bump might be worthwhile as long as you’re selling the 1070ti to recoup otherwise don’t bother.
