Is it possible for a motherboard supporting pci express 16x v2.0 max to display 4k resolution using a graphical card that works on v3.0 ?
Thanks for your help.

Of course it is. Why wouldn't it be?

Because I suspected that a motherboard that support a version 2.0 max would not work with a graphical card with version 3.0 (incompatible versions, or reduced performances). In other words, what will be the results of this difference? – Cyril N. – 2015-09-30T09:04:10.543
1PCI Express v2.0 x16 slots are fast enough for even high end graphics card throughput. But I can give you a more precise answer if I know what graphics card, motherboard, and CPU we're talking about. – David Schwartz – 2015-09-30T09:07:25.530
Cyril, these tests will probably be of interest: https://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/

The main purpose will be work (web development), no game (ok well, maybe some flash game at most, no Crysis and cie). But I still need a good quality of image. That's why I'm asking these questions :)

@DavidSchwartz Awesome! Thank you very much for your help :) – Cyril N. – 2015-09-30T09:19:48.057
PCI-e is backwards compatible. So a PCI-e v2 card will work in a PCI-e v3 slot. (Though only at v2.0 speeds). – Hennes – 2015-09-30T09:09:05.943
