Is this PCI 2.0 or 3.0?

2.0 Note: Buyer Beware, The ASUS HD7750 I purchased failed after six months and ASUS would not to replace the card, under their factory warranty

All I know is it is a PCIe card. So if you have a PCIe slot I'm pretty sure it is.

I'm running a 2.something card so I'm not 100% sure. If it doesn't say so in the specs I'd keep looking for one that specifies 3.0

Yes, all that happens is that the Graphics Card steps down to run onto PCI-E 2.0. The only difference is the bandwidth, PCI-E 3.0 has double the bandwidth of 2.0, so they are interoperable, but only top tier cards get anywhere close to saturating either bus I believe, so don't be nervous.

I believe it is a PCI card. Bought it a while back and returned it because my motherboard only had PCI-E slots. Hope this helps.

its 2.0 but its not that much of a difference, yes it will support 3.0 gpus I have a gtx 770 in mine works great difference in performance of 3.0 and 2.0 is negligible at this point

I can't believe the misinformation here. At out current time, only a top, top end GPU like the GTX 980 or 970 will make use of PCIe 3.0. Yes, 3.0 does double the speed of 2.0, but nothing actually makes it necessary that plugs into 3.0. At most, you might lose a frame or two per second in a game by running a 3.0 card in a 2.0 slot, if that. All of the available bandwidth in PCIe 2.0 has yet to be used. So, you will be just fine!

yes and no , there are 3 versions of this board, this one does not, a previous version of this one/less the pcie x1 and does have 3.0 support ,slot and the first version (not R2.0 <--does not support PCI-E 3.0 (2.0)It really depends on which one you have, this one below does have,,,http://www.newegg.com/Product/Product.aspx?Item=N82E16813131969

Yes. This GPU conforms the the PCIe specification which is backwards compatible with previous versions of the specification. This means that this GPU should be compatible with any motherboard that has x16 sized PCIe slots. PCIe 3.0 does have increased bandwidth over PCIe 2.0/2.1 and while the card is technically a PCIe 3.0 card, it will work just fine in the PCIe 2.0 x16 slots on your motherboard and there will be little to no perceptible performance loss.

Yes, this card will work fine in a PCI-E 2.0/2.1 Slot. I've used many PCIE 3.0 Cards in PCIE 2.0/2.1 slots with no problems.

PCIe 2.0 works just fine (I ran Crossfire with this and a Tri-X on an AMD system with PCIe 2.0).

PCI Express 3.0 x16. Yes. Great card for money. My computer runs like a dream.

it depends on it pci expess 2.0... it has to the do with the right voltage if it is compatible...if its 3.0 it dose not work ...3.0 is another voltage....

It would work. Buy PCI express 3.0 if you can afford it. I don't have 3.0 however and the card still screams.

I believe I can only answer one question here. All PCI-E editions are backwards compatible with their previous version. 3.0 &gt; 2.0 &gt; 1.0. I don't know the other answer though, sorry.

It is a PCIE 2.0 card. This PCIE 2 card will also work in a PCIE 3 bus because PCIE 3 is backward compatible and will accept PCIE 2 cards.

Yes, PCIe 3.0 will work in 2.0, just at half the speed. PCIe 16x 2.0 is the same as PCIe 8x 3.0 Research has shown pretty conclusively that no modern video card experiences any sort of slow down until it is under PCIe 2.0 at 8x. In other words, the card should run absolutely fine and at almost no appreciable loss in speed (unless you are trying to run two or three together, and even then, it would be under 10%). Hope that helps.
