Two different GPUs for Keras (Python)?

One question guys, someone knows if it should be ok to get one more GPU of type Nvidia Geforce GTX 1070 (gaming version), given that now I have GTX 1070 Titanium? They don't have another Titanium card available here, so I have to get a different one, but closely similar, and I wonder if for using Keras (with TensorFlow backend), will it work fine? They are not exactly the same cards, but similar enough maybe. I want 2 GPUs for Keras.

I tried training with a 1080 and a 2080 ti and I found that I didn't get any speed up from multi-gpu training because the 1080 acted as a bottleneck. So I while I think this would work fine, you would be better served to run a different model on each GPU rather than trying to train across GPUs.
