So I ordered a motherboard from Newegg for my first build, but I accidentally bought the P8Z77-V LE instead of the P8Z77-V LK. I understand that the LE has advantage over the LK in the TPU switch, but the LK has the ability for the SLI for PCI-e 3.0 x8/x8, whereas the LE only has one PCI-e 3.0 slot. I have the GTX 660Ti Superclocked + 3GB (PCI-e 3.0 x16). Should I have an RMA for my Mobo and get the LK for the future of SLI, or is SLI not necessary?

  1. SLI is not necessary unless you plan to use it. Your LE is a fine board with a single powerful GPU.
  2. Ok, but might it be a good idea to have SLI to "futureproof" my setup, or might I get away with a single GPU until I want to upgrade in the future, possibly to well, say the Haswell chipset or something even further down the line?

    If you're going to upgrade to Hanswell later on, you'll need to replace the motherboard anyways. the 1155 socket isn't going to be supported by any future cpus.

    And IMO, it's a lot better to upgrade your GPU by selling the current gpu and then buying another single card GPU. The drivers for CFX/SLI for newer games are generally terrible and doesn't perform much better than single card GPUs until a month or two after release when new drivers comes out to support CFX/SLI for the game.

    And there really isn't any future proofing in PCs. Only thing you can do is buy in when a new socket comes out and upgrade to the next generation of cpus a year later. As long as you're have the latest PCI-E slot, it should be fine for 3-5 years before they update the standard again...
  4. Agree with above, it is going to be a while until the GTX660ti is not going to make it on single monitor gaming. When that time comes you will be looking at least 2 to 3 generations of GPU's in the future and possibly a full system upgrade.
