I would leave both, 980ti going to be powerful enough for most games for at least a couple of years. Xbox Slim unless space is a real issue, is a pointless purchase.
IF PS4K defines the new minimum hardware and Maxwellv2 ends up like Kelper, 980 ti may not be enough.
There's enough hardware difference between Maxwellv2 vs Pascal e.g.
Kelper has 192 CUDA cores with 256 KB register file per SM.
Maxwell has 128 CUDA cores with 256 KB register file per SM.
Pascal has 64 CUDA cores with 256 KB register file per SM. This is AMD's GCN CU like i.e. 64 stream processors with 256 KB register file per CU.
Pascal's SM has CUDA cores : register file ratio similar AMD's CU stream processor : register file ratio.
Another problem for older NVIDIA GPUs are Shader Model 6.0(SM6) which exposes wavefront programming model and this relates to CUDA cores/stream processor : register file ratio and SM6 optimisations.
