Well just tried Rise Of The Tomb Raider and it's still a mess of frame drops and stutter.
I have noticed though that one of my GPU's is hitting 89c whilst the other stays at 74c max whilst playing it, with a ambient room temp of 25c.
There is nothing I can really do though at the moment to lower those temps though, as I cannot put more fans in the pc and I all fans are already running, at 12V via molex adaptors.
I think I will just have to save some money up and buy some Waterblocks for them but it's the last time I buy a card with a aftermarket cooler on them, and instead will just go for reference coolers in the future.
Although the clock speed is nice out of the box max on ROTTR is 1316Mhz on both cards without me touching them, I would prefer the temps to be abit lower.
