PCI e slots

[8951903782]

I have a pc without a GPU and i thinking about opening it up and putting a gtx 1050ti or a Rx 470 with a external psu.

but the rx 470 uses PCI-E 3 and i am not sure whether my motherboard has a PCI-E 2 or 3.

So is there any way to check that?

How many fps can i lose in games if i use PCI-E 3 gpu on PCI-E 2 slot?

Your framerate more than likely will not suffer.

 

PCIe 2 x16 = PCIe 3 x8

PCIe 2 x8 = PCIe x4

 

If it's PCIe 2 x8, do not worry.

1) I think PCI is compatible with any version

 

2) you will lose almost nothing

It shouldn't be an issue so long as its at least running at 8x (Which it probably is).

You'll be fine.

Thanks, how much of a bottleneck am i looking at with a rx 470 or gtx 1050ti and a i5 3470S

[kameshss]

nah. you'll be fine. It'll work with either of those PCIe versions with no loss on performance.

pretty much nothing.

[8951903782]

Also how much fps am I looking at in AAA games in 1366x768 

how many fps in cs go

[8951903782]

Also is i5 3470S good for gaming on 1366x768

Is there a way to check what kind of slot is in my computer without opening it up?

[8951903782]

Please Help

Just tell us what CPU you have, and we should be able to figure out very easily whether you've got PCIe 2.0 or 3.0.

 

Edit: Oh, is it the i5-3470S you asked about? I believe that was the first generation of products that had PCIe 3.0 support.

Even if a cpu supports pcie 3, the manufacturer might not implemented to keep costs down.

So is there any way to be sure?

That seems unlikely, but if that's the case then I don't know. Surely there must be some documentation that came with the motherboard or the PC as a whole (if its a pre-built) that would specify this.

 

But as the others have said, putting a GTX 1050 Ti or RX 470 into a PCIe 2.0 x16 slot is not going to result in a meaningful framerate difference. Every so often a tech site benchmarks this and usually finds a difference inside the margin of error when using any single card:

How do i find out if its 4x or 16x or 8x?

[8951903782]

Help?

Can you access the internals in order to take a picture? If so, please do and post it here.

Found the paper for the pc and its say there's one PCI-E slot x16 and 2 PCI-E slot x2.

Will the GPU be electrically fine even if the slot is PCI-E x16 gen 2?

The gtx 1050ti depends on the PCI-E slot for power so will it be fine with a PCI-E x16 gen 2?

Yes, a PCIe 2.0 x16 slot will work fine. I don't think the power specifications have changed between 2.0 and 3.0.

Thanks everyone.
