Will my AMD fx-8370 Bottleneck?

[imokgoca]

Hey,

I was just wondering if my fx-8370 (stock) would Bottleneck MSI 970 SLI. Currently i own 1 MSI 970 and i was thinking of getting 1 more, but im not sure about the bottleneck. And is my psu good enough to handle SLI 970? Thanks

My setup:

CPU AMD Fx-8370
GPU GTX MSI 970
RAM CORSAIR VENGEANCE 16GB 1866
PSU: Corsair cs650m

Yes.

It definitively will.

I suspect it would.
Depends on the game of course.

To help clarify your CPU/GPU options, run these two tests:

a) Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You could also experiment with removing one core. You can do this in the windows msconfig boot advanced options option. set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.

If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.
