SLI-ing two GTX 460s and the Benchmark score

[dsiglin]

I just finished my first SLI build and ran Futuremark's 3D Benchmark. Would you mind taking a look at the score and letting me know if it seems about right?

I'm not really sure what it should be, I just want to make sure everything is acting as it should. According to Benchmark the score is low. Here's how my machine compared to similar machines:

Both 460s are Galaxy 768mbs.

Thanks in advance.

Forgive my inexperience but what would be some boards that run x16 on both and is there a huge difference between x8 and x16?

A PCIe 2.0 GPU running at 8x will barely be any slower than a 16x. With a GTX 460 it will practically be the same with no FPS loss.

The 3dmark11 scores between the 16x and 8x are nearly the same, even on a 6990 or 590.

Im someone who was content with 30fps, I just happened to have enough money to treat myself to sli so I'm not going to complain if there is a slight advantage for x16 boards. Thanks for the info though, do motherboards that have dual x16 normally tout that fact? Just wondering how I would know looking at a product on a website.

 

[gmcizzle]

Yes they do, but only because the LGA 1155 boards normally have 8x/8x and those that have 16x/16x are $300+ special enthusiast ones. On LGA 1366 16x/16x is more of a standard. Most sandy bridge users agree that running 8x/8x is not really much of a bottleneck vs. 16x/16x, at least with the current generation of cards.

No prob

Ok, one last question.

Would I be better getting two 1gb 460s or two 1gb 6790s or two 1gb 6850s?

6850 is slightly faster than a 460
