Motherboard with pci-e 2.0 and graphics card with pci-e 3.0
My question is, will the same GTX 1660 have a strong performance loss if it is inserted into the pci-e 2 slot? Actually, 1060 is in the plans, but more powerful brothers are also interestingfrom none to 10% is possible empirically from the ceiling. I think with 1080 and 2080 the real express 2.0 will already be more strongly felt in not new games and high resolutions. and for 1060, given that it is old and weak at maximum graphone, then probably not. well, and there, for those who like to ride 240 hertz at the minimum settings, I think there will be some loss in relatively new games.
The more data is transferred over the bus, the better it is required, elementary resolution is 4k vs 2k with the same card - different volume, one less, the other more. Another bus is important for working with large vst, rendering. For games 2.0 X16 is enough or 3.0 X8.
