I am tempted to try Tri-Fire....

post #1 of 4
Thread Starter 
...but I have a few concerns/questions before I do. I am planning on getting a 1GB 5870 (probably from Sapphire) some time in Feb. or Mar. or sooner; idk. It looks like Tri-Fire seems to be better than 2x5970s. I have a feeling I'm gonna be tripping my circuit breaker a lot more often

Concerns/Questions/Thoughts

1. Does this setup tend to suffer from microstutters/other issues? So far, my 5970 hasn't encountered many problems that couldn't be resolved. For instance, some games run better with Catalyst AI enabled and others with it disabled. ATI Tray Tools ftw . EX: JC2 and BC2 run fluidly with it enabled. Some of my indie games run better with it disabled.

2. Would I have to connect 1 monitor per card for my dual screen set up or both monitors to a single card (either my 5970 or 5870)? I think I should be good but I'm not entirely sure. :/ Also, I have no plan to set up eyefinity

3. Is it ABSOLUTELY necessary to match the clock speeds of both cards? ATM, my 5970 is OCed to 900/1180@1.187v. Could I have these cards at different clocks? I ask because I think the 5870 (generally) can OC higher than my 5970. Will I encounter any OCing issues with this setup? Can I OC each card individually in MSI Afterburner? Or should I OC individually and flash the BIOS with the OCed clocks and voltages?

4. Or should I wait and invest in another 5970+1kW PSU? Of course I will be OCing them if I go this route! . Maybe might get a physx card when there are more games that support it.

5. I don't think I'll have any potential bottlenecks but I could be wrong. CPU is at 4Ghz (191*21) w/ 1.296v (from cpu-z) and RAM is at 1150@7-7-7-12. Yes I know my RAM has a weird clock. Im experimenting or something >.>

And as usual, I appreciate any input!

1. i have never had any issues with microstuttering. i did have some issues with starcraft 2 when it first came out had to disable the AI, but after a few patches i've not noticed any problems.

2. one monitor on the port of your main card and yoru good to go nothing else is needed.

3. it's not necessary to match the clock speeds, but why overclock high when you have cards next to each other heating up. might as well stay as the same clocks.
4. your psu wull be able to handle tri fire with no probs.
5. dont forsee bottlenecking being an issue

when i had my 5850's, msi afterburner would automatically clock both gpu's the same.

Just to clarify so I don't confuse myself, I can still connect my 2 monitors to my main card (5970) right? Or will I even be able to use both of my monitors?
