TriFire - Should i go 5970+5850 or 5870?

[douglatins]

The 5850 are a lot cheaper than the 5870 over here, but i am concerned that is not officially supported, which one should i go for?

[TRIPTEX_CAN]

If the 5850 you use can match the 5970 clocks then I'd use that. I don't see any reason why a 5870 would be necessary.

I'm pretty sure you can, And I'd go for it personally.

I CF a 5850 and 5870, and the 5870 usually runs at about 96-97% gpu useage while the 5850 is at 99% (clocked identically), so my guess is you'll sacrifice only a few % performance (2-5) by buying a 5850 over a 5870 to cf with.

all in all tho not sure about the gains in Trifire, but again, I'd go for it

I saw a review once that had the 5850 being the the better fit with the 5970. If you go for a 5870 you would be wasting your money

i use 2 5850's in crossfire, and just as a quick bench. i use the toxic editions by saphhire, i get around 80-120 fps at all times in bc2 multiplayers, single player, there beasts. same in avp over 100fps at all times

I get that too with the 5970, hat setting? I have all high, 1920, HBAO 2AA and 16AF, bu I usually turn Vsinc on to save some power

Oh, and super jealous of toxic cards, they kick serious ass

not to stray off the main topic but it would be nice if i could unlock the voltage without flashing em, which im not gonna do, lol

What should i expect in temp increase in my 5970?

[wolf]

with a 5850 under it the fan should still be able to breathe really well still, given the different lengths of the cards, maybe 5 degrees tops is my guess.

I have a 5970 with a 5870. Was using 5870s in crossfire so it made sense for me to stick with the 5870. I will say that I got a huge bump on 3DMarkvantage. Went from 27,500 to 34,600 and change. I run my 5970 at 830/1120 and downclock the 5870 to the same. I am using H20 so my temps are cool. Games are super smooth. Crysis is maxed out on all settings. I am running the 10.3 beta drivers. Will try to bump the clocks up higher this weekend. May also drop in the other 5870 to see what happens with quad fire before I sell it.

I'm on 5850 crossfire and was wondering what would the performance increase be if i added a third 5850. Is it really worth it or just showboating? I have no issues on any game currently - it was more a thought for the future.
