Instruction: Answer the given question by extracting information from the supporting document.

Input:
Question: Is this a x16 (16 lane card) or an x8? The pictures look like an x8, but none of the documentation gives that specification.
Document: This graphics card delivers excellent performance for the price. It is not targeted at gaming, look elsewhere if that is your need. Plenty of GPU power for photo and video applications that can utilize the GPU. Low power fanless design makes for a quiet system. The 2GB of onboard video memory is plenty for running Windows guests in virtual machines, which can use considerable graphics memory. The card has a gen 2 PCIe x8 interface, half of what is the norm for a graphics card.
I tried to do the rebate but it is really a $10-$30 rebate like they had in November, and it is $10 for this video card, not $30 like amazon website says. I didn't find that out until further along in the online rebate process. I still like the card, just don't expect to get it for half price like they advertise.
I don't feel like I'm running an old budget rig - not at all. And the cost was only $64.I'm very happy with this card, I recommend it to budget PC hobbyists or people trying to get a few more years out of their gear, it certainly is an excellent choice for a SUPER_DUPER media center like XBMC, and I give my thinks to ASUS for producing such a great budget card.
After having two video cards fail due to fans that sounded like a jet on take off I searched for a fan-less option. This did the trick. Totally silent. I was a bit concerned regarding how hot it would get without a fan but this turned out to not be a problem. Using the utility software included I am able monitor temperature. Right now it says 34C so no problem. Running Windows 8.1 and mostly just low demand office and browser software.
It's nice to have such a modern powerful card so cheaply and quietly.
This card, which I bought for $64, is replacing an Nvidia 8400 1GB series, which I'd been using for 4 years or so.
Needed a card that would handle 3840x2160. The Kepler version does. I don't game and the performance is fine for the type of work I do.
With the GT630 GPU it is all silky smooth, with the GPU never above 50% utilization. I recommend this card for use in mediacenter PCs. I am quite happy with it!
384 CUDA cores speeds up rendering time. Best card for the price with that many CUDA cores. Easily fit into my Antec 300 case.
Excellent video card however it is advertise as low profile and it does not come with the brackets to install it. You have to buy low separate profile brackets thats the reason for my 3 stars.
Answer: I had to return it because it was too short and my system didn't support it. I'm pretty certain it was an 8. Definitely not a 16.
