Not quite, a 1080 ti is basically the same performance as a 2080 but not even close to a 2080 ti. The 2080 ti is basically doube the 1080 ti in terms of techincal specfications, more specfically more cuda cores, texture units, vram and clock speed itself. Additonally the gtx 1080 ti provides the 16NM FinFET architecture rather than the 2080 ti superior Turing GPU Architecture and when comparing graphics cards some of the most important factors is the architecture. When comparing the gtx 1080 ti to the 2080 there's basically no difference.
But you are correct, a 1080 ti will suit your needs just finely unless you want to experience 4k vr or the amazing ray tracing capablabilites the card offers.
