I stumbled upon PCIe 4.0 also. So far have found this info;

PCIe 4.0 will essentially double the interconnect performance bandwidth of the current 3.0 specification, from 8 gigatransfers per second (GTps) to 16GTps. In addition, it introduces new technologies to enhance power efficiency: the use of an L1 substate that drastically lowers power use in idle mode; half-swing and quarter-swing, which cut power consumption by 400mV and 200mV, respectively; and high-speed data transfer bursts with minimum idle power.

As with previous generations of PCIe, PCIe 4.0 will be fully backward-compatible, so devices designed for earlier specifications will still operate correctly with the new technology. It is also expected that the next generation of computer processors will offer support for it, though the two announced this week—Intel's 7th gen core and AMD's ZEN will likely be excluded, as the first products using them will be released before the specification is finalized.

Which causes great amount of thinking, we have one computer that seriously needs replacing. Do I replace asap, end this year or early next year OR wait until PCIe 4 and compatible components are released. [???]

Interesting... As someone who's only spent about a year with his first rig, I would assume that this new development will bring about new motherboards?

Dumb question, but I have to ask. :)

I would wait as the new throughput will make ED and other games fly.

That it is and its the one thing that makes consoles still sell although with the current crop (XBox one, XBox One S, PS4, PS4 Neo) things are getting a little fuzzy to say the least.

Yes it will bring in a new series of boards that accommodate the new slot, initially they will be high priced along with components that need them but like the current components prices will fall as everything moves forwards.

Fair play. Looks like I'm still sticking to my trusty MSI Z97 GAMING 5 for a while yet. A 1060 is all the upgrade I need/want for a fair bit.

But good to know what my second rig, when the time comes, will involve. Cheers.

It is backwards compatible so no reason on that account. Remember this means that PCIe gen 3 hardware will run just fine on gen 2, and gen 1 for that matter, heck when it comes to graphic cards, even the most modern ones 1080 gtx or titan, still do not use all the bandwidth so gen 2 isn't even a limitation currently, it 'might' become it when DX12 takes full hold with its multi GPU, because it communicates via PCIe between the variou GPU's but other then that....I really do not see it.

The computer that needs replacing, needs total replacement. Early i3 CPU, DDR2 RAM, GTX670 GPU which was an upgrade 4 years ago, need I say more.

Thanks for the links (I only knew of French websites)
