5870 (5890?) & 5970 (5990?) trifire combo

[MaxSten]

I was wondering if a combo of 5870 and 5970 isn't an ideal setup?

I mean if you hook up the monitors to the 5870, then this is the card which will be used for games which can't use CrossFire/TriFire, and then if the game then accepts CrossFire/TriFire then the 5970 will also kick in.

Or am I wrong?

And ofcause a 5890+5970 or 5890+5990 is even better, but 5890 and 5990 isn't even on the market yet. But it's still worth a though being able to combine these bruteforces

Is it even possible to do these kind of mix-ups? And if yes - are there any benchmarks for this anywhere, because I can't really find any, since most is 5970+5970 or 5870+5870 ...

Thanks in advance

yeah you can mix the 5970 and 5870 without any issues.. cant say anything for the 5890 because its all going to depend on if its running a completely different GPU.. though im not sure if the order matters if its the 5970 or 5870 thats the primary.. but some one that actually runs this setup can answer that better then me..

5970 and 5870 work quite well together, however it does require some tweaking and annoyances if you want to get the clocks on both cards to be equal. I always ran the 5970 as the primary card, only because it got better cooling in the top slot.

I just got my 5970 back from RMA and I'm considering trying to trade the new one for another 5870 since I've gotten used to how quiet the single 5870 is, plus two 5870s will definitely be fast enough for anything. Unless you're benching Crysis or something there really is no use for the 3 GPUs. If anything just running the single 5870 has been the best experience for just playing games since I don't have to worry about temps or fan speeds or anything, it just works smoothly on it's own.

Abit667 do you have any benchmarks of some sort?

Have you tried it with EyeFinity? I'm just thinking that maybe 5870 CF isn't enough for 5760 x 1200?
