The 1170 has not yet been released. Any site claiming they have received an 1170 to test (and that the numbers are going to stay constant) is likely looking for attention. I'd expect the 1170 to perform between the 1080 and 1080 Ti, nothing higher than that. Also, the 6500 will be fine for most cases, except for gaming at very high refresh rates. It all depends on what you're currently running. A full system spec list (including the monitor) would help me better inform you.
WCCF seems to clarify this in their article: https://wccftech.com/rumor-nvidia-turing-gtx-1170-benchmark-leaked-faster-than-1080-ti/
