Help me choose new GPU please

[GitGud]

Ok this my 1st post here so hello people of Linus Tech Tips forum.

 

I got the itch to update my GPU finaly from my old GTX 650 1GB that has served me well but needs to be retired. Options ive been looking at are as follows: GTX 1050 Ti, GTX 1060 3 GB version, RX 480 4 GB. My most considered option ive been thinking about has been the RX 470 since it doesnt fall too far back from both 1060 and 480, but i cannot decide whether go for 4GB or 8GB model for future proofing cuz im planning to use it for atleast 3 years.

 

Any brand unbias suggestions will be welcomed.

GTX1050TI

I didn't choose the 8GB version as it's still kind of expensive

The 8 gig RX 470 is 232 € here while 4 gig around 190 - 200 €. I already bit the nail by not going with 2 GB GTX 650 back in the day which would help me a lot in modern titles today copmared to 1GB. Just wanna make sure if 4GB will cut it for atleast Low video settings gaming in games 2 - 3 years from now.
