Pci-e 2.0 or 3.0?

[Gustavss14]

Hello. Should i go for PCI-E 2.0 or 3.0?

 

Becuse i can get the PCIE 2.0 cheap.

 

Looks like the 3.0 doesn't make a difference http://www.techpowerup.com/157253/PCI-Express-3.0-Has-Zero-Performance-Incentive-for-Radeon-HD-7970-Tests.html

 

But maybe a driver will fix this? http://www.asus.com/Motherboards/Intel_Socket_1155/Maximus_IV_GENEZ/

If the option is there, and there are no ramifications with choosing one over the other (ie, they're the same price, same quality, etc.), you should go with the mobo with pcie 3.0. But you mentioned the 2.0 is cheaper - how much cheaper are we talking here?

For what purpose? Graphics cards?

[Black64]

There is almost no difference, just get the 2.0

Almost half price..

As far as I know PCI-E cards have yet to fully realize PCI-E 2.0. IMO, it doesn't really matter if you get a board with PCI-E 2.0 or with PCI-E 3.0 considering that by the time cards that can truly use PCI-E 3.0, better mobos will be out in the market. However, if I could get a board at the same price, then I would go for the 3.0.

Definitely go with the 2.0 board.

Go with the 2.0 then. pcie 2.0 still hasn't been fully saturated, no point in doubling the cost for 3.0.

2.0. If pci 3.0 had something like a x32 slot, it would be a different story.

thats funny, the total bandwith is not used in 16x.

PCI-E 2.0 will be enough for next 1 year at least.

Depends what cards you use because there is the very real possibility of a 7990 or 690 being able to saturate a 16x pci-e 2.0 slot (or equivalently a 8x pci-e 3.0 slot). Normal single gpu cards will be fine in 8x and 16x pci-e 2.0 slots for some time.

 

You may also find a board with support for cf/sli 8x 3.0 cheaper than the effective equivalent 16x 2.0 board. Same bandwidth (with an ivy processor, when they arrive).
