Re: x58a-ud3r and tri sli

You can SLI different cards? I mean you are asking about 2x9800 right, with 260?

It will be PCIEX16_1 running at 16X, PCIEX16_2 running at 8X, and PCIEX8_1 running at X8 as well

You want to use slot PCIEX8*_2, so your first card is not cut down in lanes.

It is only possible though to run x16/x8/x8

Ohh ok, 3 x 9800 then? If so go for it, should give you 1/3-1/4 higher score maybe.

I ran triple 3870's for a while, scores were about as expected. One card score + second card = usually close to double score. Adding the third card usually added half or a little more of one card score to total of first two cards (Sometimes less, sometimes more)

Of course though, I think I did that on a x4 slot with the third, so it may have been a little bit limited.

Ya with 2x 260 you should get 36,000 or more at least

Test them out and see how they do, then you will know for sure

A lot easier on the old PSU too with two 260's
