my question is the actual slot is always PCIe, as in, there are no physical differences between the PCIe 2.0/2.1/3.0, right? what changes is how the processor/motherboard supports it, right?

i'm asking this because i want to do a bit of casemodding, i've always found it silly how graphics cards look badass but are mounted upside down in the cases and i just found out today that there are flexible PCIe extenders which i could use to mount my graphics card facing up, or sideways, or upright or however i feel it looks best.
but the extenders i'm looking at dont say if its 1.0, 2.0 or 3.0, because its all the same, right? the extender wouldnt change which type of slot it is, because that's the processor's business, right?

If you motherboard is 3.0, the extender will "utilise" that specific bandwith.

hmm didn't actually know there were pcie extenders. Im not really sure but it looks like they might impact performance, as there can be a lot of "cross-talk" between the wires. This is why PATA was much slower then SATA, even thought it had a lot more connections. I would love to see if anyone has had experience with this

im not sure, don't quote me on that. This is something that only a person who has tried it will know

i got this idea while watching linus tech tips on youtube, he's doing a coverage of pax2013 and he showed a thin PC from ibuypower

they have a titan on it, and i'm guessing they are using some sort of extension cable, so it cant be that bad... unless they had custom-built wonky L shaped motherboards just for these computers....

i guess i'll buy one and benchmark with and without it to see.

does that seem about right?

or would it be something like this?

(i thought the ribbon cable would transfer the 75w from the pci o.O why does this one have a molex?)

I guess they added the molex, incase the gpu decides to draw a lot of power from the pci express slot, which can melt the cable. Most modern gpus only get about 20W from the pci slot, so you should be fine, but the one with the molex seems safer. If you are worried about neatness, get the one without mole
