Fixadent :
Is the regular GTX 1080 faster than the 980 Ti, and by how much, in percentages?
If the 980 has a good oc(~1500+ mhZ) it is roughly 10% faster than a 1070 and the 1080 is about 20% faster than an oc 980ti. This doesn't seem huge, but the 1080 is clearly the better choice due to power consumption, better dx 12 support and more, faster, memory(gddr5vsgddr5x).
Edit-reccomend 1080 for 144hz 1080p Ultra settings.
