Will a i5 or 955 bottleneck a SLI 460?

Well, i guess looking for a second opinion, will an i5 or 955 bottleneck a 460 in SLI?


also which do you recommend? the jump to intel worth the price? which i5? will amd suffice? im just gaming and web browsing

i do plan on OCing the processor and 460s

thanks for your help guys!

    LOL well thanks
  2. You don't have much of a selection with AM3/SLI chipsets. So I would go with a gigabyte/asus p55 board and the i5 760. Both companies make those boards very o/c friendly that support sli/crossfire.

    well, im fine with the Asus mobo, AM3 with SLI

    if i go with an i5 im worried about having SLI in 8x i know its a small performance difference but is it worth the jump over?

    Do you already have a system?

    not yet, im just planing on my build, i will soon, but for now im just using a laptop

    so do you think the jump to i5 is worth the loss of dual 16x PCI-e slots?

    there are a few LGA 1156 boards that can do x16/x16, you just need to pay more upfront ;)

    personally I wouldn't worry about the performance hit, even at 5/6% at the most you can always overlclock the GPU's and reduce that percentage/gap. Its not like your games are going to lag, 8x is plenty unless you absolutely need to get the highest benchmark score you can possibly get.

    That doesn't make sense. If the graphics card is maxing out the bandwidth of the 8x slot, overclocking the gpu will do nothing because no more data can get through.....

    Anyways, having a fast cpu is more important than having a 16x/16x.

    Zip , use common sense.

    For example lets say that he gets 80FPS with and x16 slot and 77FPS with an x8 slot, well all he has to do to reach 80FPS or beyond is raise the GPU clocks a bit and vualaa problem solved ;)

    that doesn't make sense because then that would mean that users that run their GPU's in x8 slots would not see any FPS gains when overclocking the GPU which is false.

    The issue that happens from having 16 lanes to 8 is technical and complex.
    There is two way communication, through the pci-e controller, cpu, gpu. They made the electrical specification larger to stop 'potential' bottlenecks. Overclocking the gpu, speeds up gpu performance regardless.

    So if your PCI-E 1.0 4X slot bandwidth is maxed out, overclocking your gpu will give you more fps?

    That's great you have an opinion, a bad one at that. Would love to see a link that says to overclock your gpu if your 4x slots bandwidth is maxed out.


    LOL


    Primary GPU's do not go in x4 slots, these are normally used for PhysX cards which need no overclocking whatsoever.
  11. So you dont think that you would get better performance with gtx480 in SLI, instead of gtx460 in SLI because dobble 8x lane setup is maxing out the bandwitch?

    Pls make sence. Ofc. you will get performance boost when overclocking gtx460 SLI cards in 8x setup.
  12. There is a new hack that is going around that is busting the myth that one needs a Nvidia or Intel board to run sli. I tried it this morning and it works....
