Will an overclocked fx 6300 to 3.8ghz bottleneck an r9290? I would oc more but I am working with an msi 970a-g43 mobo so I do not want to push any farther then the oc genie II( which is 3.8ghz) I have read at stock my cpu would bottleneck the r9 290 to about 80% perfermance, so what can I expect with this slight oc? I am now going to attempt a greater oc with hyper 212 evo cooling solution
