  1. Is it OCZ?

    And I'm pretty darn sure you can't run 3 550Ti's in SLI; they only work in 2-way SLI.

    yes it is but might be replaced as it sounds like a jet. i swear ive seen it done not sure why it wouldnt
  3. a 550ti can run ~140 watts each for 420 watts of power consumption. and given that motherboard will run x16,x16,x4 you're what? running two in SLI and one physX?

    running x4 in PCI 2.0 will take a performance hit.

    meh.
  4. would it be worth it running two sli and one physx am i going to be bottle necking the cpu
  5. I don't think a Physx card in your situation is worth it. Games hardly use Physx.
  6. what is your situation now?

    if you are looking at spending money for 2 550ti, please don't, you can get a reference 7870 or nice 7850 for $250.

    if you already have 2 in SLI, don't bother spending money on a third.
