post #11 of 39
Maybe 2 7950s can hold you over till the end of the year when the 8970s comes out.

at 1080 I see that Trifire 7950s will be sufficient... Two of them will be sufficient.

At 1440... I suggest going Nvidia at that res.... Had nothing but pain with AMD with Tri-Koreans. You need a solid Dual Link DVI for proper use of that res and all adapters are meh at this time.

3x7950 allows more horsepower which for the price/performance ratio is the better deal. You get 3 7950 for the price of 2x7970 here.
adjust settings until one gets the best performance and the iq one want.

2 cards in crossfire have alot more microstuttering than 3 and 4 cards. its tested several times. go check tomshardware. this is why many ppl use radeonpro with just 2 cards, and thats crap (fps limiter).

i had 7970 cf myself, it was hell. i sold it. way too much microstuttering, couldnt enjoy games.

fps aint everyhing... theres microstutter and frametime / latency too.

benchers dont care about these things, but gamers do.

Will the 7950s have eyefinity as well?

And would be using the cards set up as one card per monitor be a terrible idea vs running all 3 in crossfire?

And if I went 3x 7950s would I just get the generic sapphires like these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006&nm_mc=AFC-C8Junction&cm_sp=&AID=10446076&PID=6146846&SID=1904qqkx92tan

Or should I be looking for a different one?

I know people were telling me the 7970 I should look for the MSI lightning or the Asus matrix platinum

I have also been trying to find the charts comparing performance but my google skills are failing on that one apparently if anyone knows of one mind linking it?

Finally is a corsair 860i going to be able to power all of this you think?

Even the 7870 got eyefinity.

Also if you are going to play games you gonna need them in crossfire ON THE FIRST card to able to play games on eyefinity.

Go read the requirements for the technology.

Now opposed to using eyefinity and just using one card per screen. How would that work out?
post #20 of 39
You cant, all the ouputs must be from the first card. You ahve 1 master and the rest are slave. So If you got 4ouputs on your master then you can only have 4 screens, if you only got 2 then you get 2. You cant output one on each acrd
