Is it worth it to get a motherboard with PCI-E 3.0?

post #1 of 7
Thread Starter 
I'm building a sandy bridge build very soon and I see this Asrock GEN 3 that has PCI-E 3.0. Is PCI-E 2.0 still relevant enough to buy a new build based upon it? Would prob be SLI'ing 560 ti's

No one is even using PCI-E 3.0 right now, it will help to "future proof" but its going to be a year at least I would imagine until it even becomes sort of main stream - of this current generation of cards, the only ones that could even really benefit from the 3.0 would be a 590 or 6990.

That isn't to say that no you shouldn't buy it, if you like the board and it happens to have 3.0 then go for it, just don't let that be a deciding factor in your buying that over something else that might be better but have PCI-E 2

Yes, it will be perfect for Ivy Bridge/Kepler/7xxx.

PS: Get some cheap chip like the i3 2100 and then upgrade to Ivy when it comes out, and stick with your single 560 Ti for the time being, Kepler/7xxx will bring some serious performance gains unlike that of 5xxx to 6xxx/Fermi 1st gen to Fermi 2nd gen.

yea you also have the GB G1 Sniper 2 and the MSI GD80 with PCi-E 3.0

i think its not really a reason to buy a board,.

The real question is:

Has PCIe 2.0 been saturated yet, now I need PCIe 3.0?

I think the only real benefit with PCI-E 3.0 at the moment is nothing, because the CPU's are on PCI-E 2.0, but with Ivy Bridge it has a PCI-E 3.0 controller. At that point the only devices that will be helped by this are high bandwidth RAID cards or USb 3.0 cards, that need the bandwidth. PCI-E gen 3 GPUs will prob be out around then or a bit after. Maybe the GTX680 will actually need it.

Thats about the best explanation you can get!
No need for it. (now)
