Turns out it was the new gpu, think I got a real lemon. At 80mhz+ on the core it would just crash, could hardly maintain 2010mhz in game after throttling I think it must have been a faulty return. Put my 980ti back in and put a hefty overclock on it(still surprises me how low nvidia clocked the 980ti knowing how much it had in the tank) and my system is 100% stable rock solid again.
Reps to the people that said just go with a two slot cooler, I feel that's where the price to performance is this gen due to the power and heat limitations of all the cards it doesn't seem like a 3 slot is worth it unless you really need that 1-2% extra however it comes at the cost of sagging and £100+ extra. I will just go with a ventus, will try get the OC version at a decent price and call it a day.
