OK my rig
16gb ddr3 ram 1600
AMD 8320 8 core cpu
512 SSD drive + 2tb storage
Asrock extreme 4 970 chipset motherboard
had GTX 960 2gb, upgrade to 970 4gb at weekend to fix problem.
Corsair New PSU 600 watt
had major problems with Forza Horizon 3 with random frame drops from 80 fps down to as low as 8 fps(1 to 2 seconds)
Battle field 4 the same.
i noticed cpu temp was at 50 to 60 idle(thought cpu throttle)
renewed paste & added an extra fan to freezer pro cooler, idle dropped to 35 to 45
forza runs 90% better
BF4 still drops frames randomly down to as low as 10 fps for 1 to 2 seconds.
temps in game max 68

any help would be great
