Computer is slower with SLI?

Ever since I installed my second EVGA GTX 275 in SLI my computer has taken longer to load everything. My framerates have been fine, I can now max out crysis at 1680 x 1050 with 45+ FPS (before it was in the 27-32 fps range). Is there any reason that my computer is acting slower than it was before that has to do with SLI?

  1. Nope, no reason it should be slower at all.
  2. If you are using a 32 bit operating system, you might be running short of memory, especially if you have other add on cards installed and/or several programs that load at startup.
  3. Im on 64bit windows 7...

    Certain programs now take 2-3 times as long to load, when I right click to get the menu it takes 3-4 seconds to load that versus almost instantly before.

    Also occasionally when i run Wprime I get like 1 second worse than normal (usually it is 8.6 seconds, sometimes the score drops to 9.6 seconds)
  4. maybe you have knocked loose the HDD cable a little bit while installing the card. Happened to me once with pata cable, it still worked but was very slow in reading/writing stuff from/to the drive. Not sure if this could happen with a sata drive, though...
  5. Everything? or just games things that need the card acceleration.
  6. What do you mean "taken longer to load everything"? Load times, ie CoD 4 maps?
    Can you give an example?
