I'll try this right now with my MSI 8800 Ultra and GTX 570.Should be fun biggrin.gif

Almost works.Once i hit the apply SLI button my screen goes black.Here's a pic:
375

Edit:Techpower up forums suspect this only works on same core cards like 460+560,9800GT + GTS250,GTX570 + GTX580 etc.I will try with my two G80 cards,8800 Ultra and 8800GTS 320.

Nice! My friend's getting a 560 Ti soon, will he be able to use it with his old 9800 GT? What's the performance like when you have such different cards together?

I guess for a 460 with a 560/560 Ti should be good performance increase because they are so similar. Right?

Basically NVIDIA physically rob people by:
- Trying to force you to match cards for SLI.
- Only allow you to connect two monitors into each card rather than three.
- Giving you really crap default VRAM for today's standards.
(I'm sure we can add more to this list)
The sole reason that I'm stuck with NVIDIA, sadly, is 3D Vision. Otherwise, nothing but a middle finger to the capitalist pigs! tongue.gif

I prefer Nvidia despite all this, TDRs aside, Nvidia has better drivers than ATI, and ATI/AMDs upper level tech support were complete dicks to me when I tried to educate their tech on why their OpenGL drivers could only make 1 call in the time that Nvidia could pump out two(almost three).

If you want a fast example, try an AMD card versus an Nvidia at the same relative "power" in any direct3D/DirectX type game, and then compare them both on an openGL game. AMD's cards will do, say, 60 fps with a minimum of 24, where as the Nvidia will be slamming at 170 FPS with a minimum of 45 FPS. ( Second Life, KOTOR, KOTOR 2, so on and so forth.)

In fact, KOTOR went on being unplayable on AMD/ATI cards for nearly a half year. That is really sluggish.

Edit; to further explain. AMD/ATI has a CAD/graphics designer line of cards called fireGL. FireGL cards have a huge price tag, AMD wants professional studios to buy the high priced cards. The only way they could do it, here lately, is by purposely hamstringing the openGL instruction sets. OpenGL, by the by, is what most of the CAD and 3D design software is made in.

AMD normal < Nvidia normal < FireGL.

You can think of it as if you had to figure out the answer to a common long division problem, versus knowing it out of memory. Nvidia's normal line of cards has more time saving computations already figured out and baked in.

Okay so i did some tests on this new SLI configuration with three games mainly BF3,MW3 and Crysis and the results werent so good.Played Crysis@1080p with SLI 8880 Ultra-8800GTS 320 setup.Noticed a 20 frame increase on all medium settings.With the Ultra alone it was around 50fps.When i changed the settings to High,the game becomes unplayable with the SLI configuration as the frame rates drop down to below 10fps.BF3@1080p was around 30fps with the 8800 Ultra alone at all medium settings.Once i enable SLI,it becomes unplayable also no matter what settings i choose.MW3@1080p with all settings maxed with the 8800 Ultra was getting 40fps.SLI and frame rates fluctuate 15-40fps.Seems like only Crysis had some benefit on this set-up.Same thing with Heaven benchmark.Single 8800 Ultra was getting 25fps on the test and as soon as i enable SLI,frame rates fluctuate from 5-25fps constantly.

Seems like only Crysis had some benefit on this set-up.

That is sad to see. I completely understand tho. How many people are working on these drivers? Just one? IMO, just getting it working is exciting, and worth mentioning. Thanks for the update ^^

So its possible to run lets say 560Ti and "760Ti" in SLI with increase in performance O_o
