Rtx 5060 ti 16gb worth it for a 1080p build?

One thing if your board is older: the 5060 Ti runs on 8 PCIe lanes. On a PCIe 4.0 or 5.0 board that's nothing, on PCIe 3.0 you lose a bit, and the 16GB card suffers less than the 8GB because it isn't spilling into system memory as often. Worth checking what your board supports before you buy.

for 1080p yeah, plenty. high to ultra settings are comfortable on it and the 16gb version is the right one to get, the 8gb card is the one people are rightly moaning about. only thing i'd check is the price gap to the next card up, if it's small it might be worth stretching.
