Hi guys, I have question.

I have 750 W Corsair PSU - > http://www.corsair.com/tx750w.html

My rig is :
FX 8320 AMD
12GB 1333mhz DDR3 Zeppelin
GTX 470 SLI
Asus M5A99X evo r2
Kingston 60GB SSD
WD Green Edition 3TB HDD.

Whenever I run Unigine Heaven benchmark or valley or etc. My GPU usage is jumping from 60-85% of Usage, and its jammy and laggy, what should I do to get the GPU usage at 99% ? To pump out the best of my GTX cards ?

Also what is probably bottlenecking my rig ? Is it RAM ? That they are not in 1866 mhz ? Or PSU probably ?

You didnt understand me, My GPU usage is jumping from 60% to 90% If they were Maxed out I would be happy.

Even though I have these GPUs outdated and old, my Benchmark is equall to GTX 760.
