This configuration has 0.4% of processor bottleneck . Everything less than 5% should not be concerned major bottleneck.
Processor bottleneck is worse, than graphic card bottleneck, because utilization of your processor will be on maximum and it will throttle other programs that are ran in background. Also you won't experience maximal performances that your graphic card offers.
