7900XTX now or wait for 9000-GPUs?

So, I'd have the option to get a 7900XTX Taichi (to my knowledge one of the best 7900XTX models) in near mint condition now for 800EUR, or I could wait to see whatever AMD is releasing in March.

According to the rumors, all the upcoming cards will be in the mid-range and have 16GB VRAM Max(?) I don't think there will be any Halo product this generation?

So is it worth getting the 7900 XTX now? Because it seems like none of the upcoming cards will outperform it...?
