That should not e an issue.
Tests pointed out that there’s hardly any difference between CPI Express 3.0 and 2.0 and also not much difference X16 and X8. So if you have 2 x PCI-Express X16 slots you should be fine !
Of cause as time progresses, the performance of the Graphics cards improve and the bandwidth of a PCI-Express Slot could become a bottle neck. However with your configuration you should be quite ok.
