The Turing cards aren't worth their retail price (especially the 2080S) IMO but I've managed to snag a Gigabyte RTX 2070S Gaming OC that a guy bought and hasn't opened for like two months, purchase proof included. Paid less than I did for my MSI 1070 Gaming X that I now sold for around 140 quid so it turned out to be the cheapest and most worthwhile upgrade ever for me.
The card runs really cool and quiet, no coil whine etc. and can run RDR2 1440p at pretty high details without problems. It's vastly more powerful than my 1070 and I can now wait to see what Ampere brings while enjoying some games properly knowing I've spent relatively little money on the upgrade
If it's not a significant step-up, I'll stick with what I have.
