This card was designed for a PCI 3.x slot. Does anyone know how much of a performance loss there will be using it in a PCI 2.x slot?

-Very minimal performance loss if ANY at all will be seen. I have posted this sites testing results that are specifically tailored to this question as well as the link to the full article that is easy to read and understand in layman's terms. I also provides comprehensive graphs showing the tests results. "Conclusion: Our testing has pretty clearly shown that for gaming using either PCI-E 2.0 or PCI-E 3.0 will give you nearly identical performance. Oddly, in some benchmarks PCI-E 2.0 was actually faster than PCI-E 3.0. At the same time, x16 was not consistantly faster than x8. Again, x8 was actually faster than x16 in many cases. So unless you care about getting up to 1.5 FPS better performance, you might actually want to manually set your video cards to operate at x8 speeds - although we really would not recommend doing so. This isn't to say that PCI-E 3.0 is not faster than PCI-E 2.0, or that x16 is the same as x8, but rather that current video cards and games are simply not able to utilize the additional bandwidth they provide. In fact, we recently showed that the performance of a Xeon Phi card is greatly reduced if you run it at x8 speeds in the blog post Performance of Xeon Phi on PCIe x8. While we recommend using the latest PCI-E revision whenever possible, if your motherboard or video card only supports PCI-E 2.0 our results show that this really is not a problem. At the same time, if you want to install a sound card into your Z87 system but doing so would limit your video card to x8 speeds, that is also not a very big problem. At most you may see ~1.5 FPS drop in performance, but that change is so small that it is very unlikely to ever be noticeable."

I am using a P7P55D-E PRO motherboard which I believe is only PCI 2 and it works like a champ. I play BF4 at 1080p on Ultra with no issues.

So far there is no performance lost with using it in a PCI 2.0. If you maybe spent $300 or so on a new motherboard with all the new stuff then there might be a performance lost mainly because of the possibility of boosted speed in the PCI 3.0. So to sum it up. You should be fine

Hi I would assume that the card would operate at pci-e 2 performance with the head room of pci-e 3 if you updated the motherboard at any stage, bit like ram.. it does the same thing when fitted to a board that can operate it at a curtain frequency ..

When running in SLI the two 16X slots will run at 8X which is fine since it won't bottleneck even at that speed. However the third slot runs at 4X which would cause a timing problem as far as know. I never run Cross-Fire or SLI. I just buy the fastest single card and go that route due to micro- stuttering. Steven Level

Yeah. I have 2 over these guys in my workstation SLI. For a period of time I had to have one is PCIE 2.0 slot and the other in the 3.0 worked like a charm. I will note though if you want to use this for solid works or auto cad. DO NOT use the newest driver. It will crash everything. Use driver 9.18.13.697 built on 10/2/2012. I love this card, great for professional use case. Don't expect super high fps in games though. This card is strictly for workstation graphics

It occupies 2 slots space and you should always plug it into your PCI-E 3.0 which usually is the first full size PCI-E slot. Pretty impressive for the thiness of the card considering how good the ACX cooler is :)

Yes, all PCI x slots are compatible with one another. The slot ultimately controls the speed though, so it won't perform as quickly as it could. But honestly, you won't be able to tell the difference.Also, the other commenter may have just had a bad experience. This card is fantastic and I've never had a single issue.

Yes it will. There is a slight performance drop associated with not using PCIE 3.0 but its negligible. I use it in 2.0 myself, works great

it will fit in any PCI slot as they are standard. Do not get it confused with PCIe. this is a whole different story. even though the PCIe looks similar they are not.

Yes definately it will work. GTX 770 is PCI 3.0 capable but its 100% backward comptible to PCI 2.0. As of now there are no cards available to completely utilize the bandwidth of a PCI 3.0 card. There are many benchmarks and threads you will find regarding this but I will say if you compare the performance of GTX 770 on a PCI 3.0 and GTX 770 on a PCI 2.0 mobo you will find that there are practically no difference in performance between the GTX 770 running on PCI 3.0 mobo and PCI 2.0 mobo.. Hope I have answered your question.

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.

It should work just fine. This card is not too demanding on power needs and your PC has the correct slot connection, etc. it's easy to install. This card doesn't get hot either as long as its not crowded and all of your system fans are flowing air.

Yes a 2.0 card will work in a 1.0 slot. You will loose a little preformance but it will still serve its purpose
737937
Yes. The bandwidth in your 2.0 x16 slot will be comparable to PCIe 3.0 x8, which is more than enough headroom. It's a great card, go for it!

I don't believe so. Generally with PCI, stick to the slot it's specifically made for.

I have not had any bottlenecking which is one of the main reasons I bought this card. I have a AM3+ board with pci express 2 because AMD has not really released any good express 3.0 boards, I heard in some reviews that there was no bottlenecking and they were right.
1817857
Yup! I have mine on a PCI-e 2.0 (x16) and have no problems what so ever. As long as it gets the juice, you'll be just fine.

It says that it takes up to Power Consumption up to 75W no additional PCIe power required. And from what I read in PC Mag your PC consumes about 70 Watts under Load so if you don't have multiple Hard drives or Using alot of USB devices you should be good with this card with your power supply. Here is the article I found in PC Mag. From what I read I would say yes it would work fine. But the PC is getting a little outdated to so I don't know how much performance you would see from this card. http://www.pcmag.com/article2/0,2817,2255115,00.asp
