Crossfire vs SLI (Motherboards)

Anyone shelled out the money for a Crossfire motherboard with a Radeon X1900XT?

How about the Sli motherboard with an nVidia 7800 or 7900 GTX?

Just wonder if Gp4 plays well on these latest video cards. I have heard, not sure how true this is, that only about a 100 games can be played on the SLI config. Anyone know?

It only offers a 30% increase in performance, which to be honest, I still don't think is worth it unless you play so many games in a day and do bugger all else :P And as you said, not all games support SLi, but I'm not sure about crossfire.

You can play GP4 and many of the new games on full detail with a 1900XT, and it's the same with the 78/7900 GTX

Actualy IIRC SLI can offer up to an 80% increases in performance, depending on the game and settings etc. Even still can u justify spending arounf £700 on an SLI setup, like zeppelin said you can play most new/recent games on full settings with either the 7900GTX or the 1900XT

80%? Where did you here that? Unless they've updated all the BIOS and configurability of the motherboards in the last 3 months, I doubt there's suddenly a 50% increase in performance in the last 3 months

@sk83k

80% , i think it gives u boast of 50% only for games not above 50%.

Got a magazine (PCFormat) reviewing the 7900GTX in front of me. Its benchamrked a single 7900GTX, and an SLI set up. Here are the results:

FEAR - 1600x1200 4xAA 16xAF

Single card 36 FPS
SLI 67 FPS -------86% increase

3dMark06

Single card 4759
SLI 8524 -------79% increase (if my maths work lol).

So in certain circumsatnces you can get big performance gain. However it also tests a 7600gt single, and then in an SLI set up. in FEAR there was no change in FPS, but there was still a 76% increase in 3d mark score

I suppose it all depends on anti-aliasing, resoultion, anisotropic filtering and especially what game you are running

Which one, x1900xt or 7900 gtx, seem to be the one to get right now?

There both much of a muchness really.

The main differnce is that the 7900 will probably give you a higher FPS, but the x1900 will give you better gaming quality.

It depends what you're after

explain? are you saying that ATi provides better graphics?

No, it seems to provide more AA and AF settings which don't have such a hammer on performance as you'd get with something like the 7900. It's kinda hard to explain, you just have to read some reviews on it, but the ATi provides more configurability as well I believe
