I'm still reasonably happy with my 660, fallout4 is the only game I've played so far that has slowed it down below 60fps maxed out; plays very smoothly on high quality 1080p so I'm happy with that and the visual differences between high and ultra settings are minimal
Not sure how much the 4.5ghz cpu is shoring it up but it certainly pulls it's weight for a 65 quid gpu!
I bought the Echo TR disc brakes a couple of years ago. Handled them perfectly when I got them but both of them started leaking and the pads (echo ones) were quite shit to be honest. But. I then ordered new O-rings (thicker), Jitsie pads from Tarty and now the brakes are immensely good. My mates even wondered how I got my Echo brakes to function that well. A fresh bleed, new pads, replace the shitty Echo O-rings with Magura ones, bed the rotor in with water and they WILL have exquisite bite and hold.
