This configuration has 16.2% of processor bottleneck .
When playing games your graphic card won't perform on maximum possible performances (won't be utilized to the maximum), because you processor won't process and deliver data fast enough. This theoretically means that utilization of you processor will be on maximum and the potencial of graphic card will not be completely used.
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.
You can resolve this by upgrading your processor or by downgrading your graphic card. Downgrading your graphic card doesn't make much sense and in that case is better to leave current graphic card in you computer.
