Hi. My friend just got two 780s and a new Gigabyte motherboard. He has this CPU
http://www.newegg.com/Product/Product.aspx?Item=19-103-...

He's getting very poor performance and he thinks the motherboard may be faulty. I thought the CPU may be bottlenecking his GPU as he is only seeing 40% GPU usage.

No this should not bottleneck the performance, what is his full specs? I hope this helps at least a little bit. Please feel free to contact me about any other questions/concerns you may have in the future. Also please remember to pick your best solution so other people may learn from your thread. Thank you for your time, and have a good day.

Thanks for the reply. I'm not sure about his specs but I know that when your GPU usage is not at or near 100% and your FPS is not at your monitors refresh rate that means there is a CPU bottleneck. Are you sure that CPU wouldn't bottleneck a card like the 780? If it's not the CPU then it must be a faulty motherboard...

Not exactly it could be the ram, motherboard, power supply, anything really that is why i wanted to know his specs. That processor is a quad core and 3.4 GHz is plenty to run a dual setup like that.

Yes, the CPU bottleneck could be a possible scenario. Dual GTX 780 in SLI is way too overkill for that CPU. The Phenom II X4 965 is significantly old now. Reason why it is discontinued @ Newegg. Also, it only supports 1600MHz or lesser. So if the RAMs are running at a different clock rate, it might be a possible that this is a hell lot of a bottleneck.

True, however we wouldn't know until he has a list of components, like i said it could be a number of things.
