Any recommendation for a graphic card which will fit at a PCIe x4 speed?

Hiya,

I was asking in the forums how to fit a graphic card into my mini PC and it seems a doable solution would be to use an available M.2 2280 slot (32Gbps) to put a converter to PCIe at x4 speed.

I think then I could try to either find a GPU with a PCIe x4 size or a cable from x4 size to x16 size and find a standar GPU (although it'd be limited at the x4 speed of the M.2 slot anyway).

I don't know anything about GPUs though. Do you know what's the characteristic I need to check in them if I know they're not going to go faster than 32Gbps?

And any specific brand/model that you could recommend to have a loo?

I agree with Gam3r01. If you have an 1151 socket motherboard that supports Kaby Lake, you could use an i5 7500 which has a pretty decent iGPU. Good enough for most games at 1080p or less. Your other problem would have been with the supplied PSU as well.

I just realised about all the hardware requirements when I bought a recent mini PC recently mainly for business purposes (like 90% of the time I won't be doing anything else other than programming, virtual machines, spreadsheets, researching, etc). But then that I bought kind of a modern pc, I thought that I'd like to give it a go with some of the new games or even try some of the basic things that have been done with Virtual Reality.

At the moment I've got an HP Elitedesk 800 G2 mini with the standard settings. i5-6500, iGPU intel 530, 32GB RAM, 256GB SSD, and I saw in youtube some DIY external-GPUs, where people were hooking them put to internal laptop ports, saying that it was possible to connect a full size GPU to an m.2 slot (albeit reducing the speed to PCIe x4), but even like that when I asked about this possibility in another question I was told that any dedicated GPU would be a lot better than the iGPU.

Yes, I'll have to research an PSU as well to power it up, bug depending on how much is a suitable card it might give it a go in the following few months.

I wouldn't mind the resolution then. Not a hardcore gamer.

But... I'd like to try some of the basics in the Oculus Rift. Not sure what's available yet, but it seems that the requirements for GPU for VR were quite demanding. Not sure what would happen if I don't have the minimum they need, if the VR apps would be just really slow, or they wouldn't load at all?

I'm still trying to setup the mini PC, and then I'll have to research more about the Oculus Rift to see where I could get some demos or some videos about themeparks and similar to see what this PC can load...

The minimum requirements for VR call for a GTX 970 or higher which you're just not going to be able to do, I'm afraid. You might consider keeping the mini for work and building something for gaming and VR. It can be done relatively cheap these days.

I wouldn't spend money to piece something like this together. It doesn't make sense when you factor in the cost of the VR gear, that you're going to run the whole thing with a business computer. If you want to do it on the cheap, consider buying a quad core desktop system used, maybe Sandy Bridge era, and pop a videocard in that. You'll have a standard PSU and standard pci-express slot to work with.
