Upgrade to Mojave

My iMac (iMac13,2; Intel Core i7; 3.4 GHz; Memory 16GB; graphics GPU NVIDIA GeForce GTX 675MX) currently runs macOS Sierra 10:13.6. I'd like to upgrade OS to (at least) Mojave but graphics GPU does not appear explicitly on Apples 'approved' list.

However Looking under Hardware/Graphics/displays I see  Metal: Supported, feature set macOS GPUFamily1 v3.

My question is whether its OK to upgrade to Mojave or are there any issues in doing so.

Please excuse me if this a daft question. I'm new to this forum.

Many thanks.
