Does PCIE Bus Supporr matter?

[LinkTheRat]

So I am new to this whole PC Building stuff. I bought a prebuilt PC not long ago and it has no graphics card. I am using a processor with integrated graphics. I wanna upgrade to a MSI GTX 960 GAMING 2GB. On the website it says the Bus Support is PCIE 3.0. Does it matter what version I have on my motherboard PCIEx16 slot or should I consider buying a new motherboard?

Sorry if I confused any of you with my attempt to explain this , hope you understand.

PCIE 3.0 can use any graphics card until 2017

Yes but if my motherboard has a different pciex16 slot version does it matter?

Basically, image the PCI-E lanes as lanes on a road

 

1 lane is 1 lane. If you add another lane, you double the data traffic, without changing speeds

Then, when you change generation, it is like increasing the speed limit.

 

When you reach a certain point, PCI-E data transfer rates are higher than the GPU can use said data.

So, anything above PCI-E Gen 2.0 8x will be fine.

When you go up a generation, throuput is doubled.

 

This means that Gen 2.0 16x is the same as Gen 3.0 8x

 

 

No, you do not need to change the motherboard

It should work fine pcie slots are backwards compatible

This makes no sense.

IN 2017 PCIE 4.0 COMES OUT, MEANING NEW GRAPHICS CARDS CAN MOVE UP FROM 3.0 TO 4.0

Does gen 1.0 exist?

Yes, but I didn't mention it, as it is no-longer supported on pretty much anything from within the last 7-8 years

They will still be bacwards compatible, you can put a pcie 1.0 card in a pcie 3.0 slot, and a pcie 3.0 card in a pcie 1.0 slot. 

 

Your previous statement implies pcie 3.0 cards would not work in the year 2017

Yes, it will bottleneck most gpus today though.

Ok , but how do I know if I got gen 1 or gen 2 or gen 3?

I only have a PCIEx16 slot. Nothing else 

Is that ok with the graphics card I currently plan on buying..? If it is then I'm ok.

Usually it is in the bios, or in the manual, but if you bought in the past year or two it will most likely be 3.0.

I bought it this year in April. So lets say it has no way of being 1.0. Does 2.0 bottleneck performance?

Sorry cause of the random text. My tablet is kinda glitchy

PCIe 1.x slots don't even work with most Gen 2 and none of gen 3 cards

With a 960 no, the only card that may be slightly bottlenecked is a gtx 1080.

Ok thanks. I'll buy the graphics card this week probably and I will update you on the situation. If nothing bad happens I'll close the topic

So I went into my BIOS and found the PCIEx16 slot speed can be only gen 1 and gen 2. 

I guess it should be ok?
