5870 TriFire vs 5870+5970

post #1 of 7
Thread Starter 
Hi I was wondering what would be more powerful: 5870 Trifire or a 5870 And a 5970. I'm Guessing that the 5870's would be more powerful but if i got them the cooling would be awful as the cards would be squished together. Cosidering Crysis 2 I want to get the best graphical experiance possible.

I will also be upgrading my psu to a Coolermaster Silent Pro Gold 1200w
Thanks,
Matt

Well. You obviously have a lot of cash on your hands.

On topic.

I believe the 5870+5870+5870 route is cheaper (maybe) But that seems like major overkill. I always thought that anything higher than 2 card CF or SLI never really improved performance that much. For cooling just make sure you have a lot of airflow.

Get a 5970 and use it together with your 5870.. Tri fire seems to be working really well

That way you get to use 2 slots instead of 3, less heat / noise

Also you need to get that i7 from 3.4 to 4.0 or 4.2... or else its not worth it

Tri-Fire is working really well with the 5xxx serie, and scaling is pretty good also. I'm using a 5970 + 5870 (all @ 1000/1200) since over 1 year already, and it's rock-stable for me. smile.gif

I can't remember the last time I had a BSOD/crash/bug/freeze or any other problem in the last 12 months. smile.gif

Problems with Crossfire/Tri-Fire are 99% of the time PEBKAC.

I currently use a 5970 and 5870 x-fire. Runs great! Im using 2 monitors. Sometimes the 5870 isnt even needed for the games (the gpu usage on CCC tells me at times 0%).
Correct me if Im wrong- but the 58xx x-fire setups give you microstutter. I experience that with mine

One thing to note.. the 5970 has 2gb or memory (or more depending on which one you get). the 5870- standard has 1gb, and other models have 2gb. If you x-fire the 5970 2gb version and 5870 1gb version, you'll only have 1gb of memory. It works like a HDD in raid. Thats a downside. In many reviews a x-fire 5870 setup is faster than a 5970 setup. When you OC then it changes things..

Yeah a 5970 and a 5870 sounds tempting but will it be able to max out crysis 2 across three monitors at 5760x1080. Because thats what i really want. Also Is it possible to have 1 5970 and 2 5870's for Quadfire?

Thanks

quad fire runs well...in benchmarks

I would dump the 5xxx and get a 2gb 6950 since you are running multiple displays and you could use the extra memory for eye candy
