some would say no. if this will be the last gpu you buy then go with the Ti. but if you plan to upgrade get the 1050 now and upgrade later passing over the Ti.
is it worth it? if you think the extra 5-10 fps are worth 45Eur then get it but its not a huge improvement.
Id take a 560 4gb over a 1050 non-ti if its exactly the same price personally.
Its swings & roundabouts generally depending on game - they're fairly evenly matched but when the 560 wins (generally vulkan & dx12) it wins big
At that res you can game comfortably with either.
The 1050ti is still worth that €45 extra though comparatively.
Hey i just found Gainward GeForce GTX 1050Ti 4GB kinda cheap. But it sais Memory Clockspeed : 3500Mhz (DDR 7G) while like asus gtx 1050ti 7000mhz is it a scam?
