So what happens if you SLI a Geforce 9800 GT & a 560 Ti?

A lot of people say that you can’t SLI two different brands of cards. But what happens if you try to?
Answer #1
What happens? You realize you’ve wasted 20 minutes of your life.
Answer #2
You’ll probably find that the 9800GT will bottleneck the 560Ti.
I SLi’d my GTX260 (dedicated physx) to my GTX560Ti, and I got 10 FPS less !!
I was better off getting rid of the GTX260 and letting the 560 do all the work.

Sorry, I think the term SLI was wrong when I said that… I meant just having the 260 as a dedicated physx card.
I replaced my 2 x 260’s with 1 x 560 (great upgrade btw)… and before I sold the 260’s, I decided to test a few benchmarks with the 260 as a physx card along side the 560, but it just didn’t work out.
Answer #5
Funny – it’s supposed to work.. Did you have it actually running in sli mode?
having one card for physx and the other for gpu is supposed to work well, but they both have to be separated in the driver, not sli, and you have to manually set physx to one card, not auto-choose.

Yeah that is exactly what I done… surprisingly it just didn’t work.
Doesn’t matter… I’ll buy another 560Ti with my xmas bonus WOOOT

Be careful – I actually did have two 560ti’s in sli, and dumped one.
Firstly sli is still very unstable, in operation and just getting it to run.
I had to faff about with all sorts of settings to get various demo/benchmarks to run sli.
For ages, Unigine Heaven refused to go sli (I can’t remember now what I did to get it in sli).
Furmark and fluid mark also had problems.
At the end of it all, One of the ‘marks gave me 265 fps with sli and 168 without it.. fast sure, very fast, but that was everything maxed out.. one 560ti is enough for 95% of current games, and seems pretty future proof.
If you insist on going the sli route, what about the new card that is 2 x 560ti’s on one? (Forget the name now..)
Answer #9
i found sli stable and worked well, but not as well as it cost… although i wouldn’t getting another 570 and running it again.
Answer #10
When it worked it worked well..
But I had some major system instability that went away completely when I removed the second card and killed sli.

You must be doing it wrong.
