EVGA GeForce GTX 680 2GB PCI-E x16 vs. x8

Hi everyone. I have a P8Z77-V LK mobo and an EVGA GeForce GTX 680 2GB GPU. My GPU is currently lodged in the PCI-E x16 slot on my mobo. I am thinking of moving it onto a PCI-E x8 slot to make room for a PCI wireless adapter I want to install later. My question is, will I notice any difference in performance from my GPU by moving it to the x8 slot from the x16 slot?

  1. The difference is so negligible that you should notice no difference at all.

    However, why not leave your GPU where it is and install the networking card in the 8x slot?
  2. Thanks for the quick replies. I actually do have a small PCI slot already open that my wireless adapter can plug into but it's so close to the GPU and externally I'll have 3 antennae sticking out, which would also get in the way of the external part of my GPU. So I figured I'd move the GPU further down on my mobo.
  3. I have a far better wireless adapter solution for you, so you don't even need to bother about the slots. I used to have a pci wireless adapter but found a far better thing.

    When i hooked this up I had full reception instead of reasonable and good (windows)
  4. Your motherboard has a gigabit LAN ethernet port. Another option would be to buy a wireless router and plug it in there. I'm not sure the reasons that you want an internal card but an advantage of an external router is that the antennas would be further away from your computer, decreasing interference which should result in a better wireless experience.
  5. My wireless router is in my den/office on the lowest level in my house and I have my pc sitting in my room on the top floor. I have these zyxel powerline av adapters (200Mbps) plugged into my router downstairs and my pc, so I thought it would give me wired LAN speeds. However, doing down/up speed tests online, I am getting about half of what I should be getting (10Mbps down but should be getting around 20-22 Mbps). I have 2 laptops connected wirelessly to my router and with the same tests, get around the speed I should be getting.
  6. In that case I would go with an external access point similar to what Tieuw posted. Though I would recommend one that plugs into your computer by ethernet cable rather than USB.
  7. You should usually get better performance on the powerline adapters than wifi. are they plugged directly into the wall socket? Dont plug them into surge protectors or 4/6/8 way adapters.
  8. Update: Ended up getting a wireless adapter via PCI-E and just installed it. Happy to say that it's proved to be successful as I am now getting the speeds that I am supposed to be getting, being connected to a 5.0GHz band. Since I don't want the powerline adapters to go to waste, I will probably just use them to hook up my blu ray player to the internet so I can watch netflix on there or something. Again, I wanna thank everyone for their input! Thanks for helping a noob like me!
