Again with the condescending nonsense, what's that about
So you've referred to two of the five games they featured in that review, that were for a brand new card only released today with beta/preview drivers. I could pick two of the other games to copy/paste quotes from:
AvP: "we once again see over 100% extra performance from doubling the amount of cards when compared to the dual Crossfire test"
Witcher 2: "The Witcher 2 doesn't actually put any display on the two extra screens in Eyefinity. However it definitely takes advantage of our Quadfire set up"
I fail to see why posting facts on the subject being discussed is condescending.
Firstly let me answer what you have posted above.
1. In every game tested
one single card was more than enough for any one.
Meaning, your argument was pointless before you even started it.
2. Adding FPS to a game that you can not see is pointless.
3. If even
one game failed to take full advantage of every last GPU you give it then it is not worth doing. Why? quite simply the price.
Using the question posed in this thread as an example - adding a 6970 to a 6990 will add more FPS
in some - noting the word
some games. However, a 6990 when working and running in a game that supports it is already massive overkill.
So that means that next up would probably be resolution. 85% of gamers on Steam run 1080p. The rest are listed as "Other". However, your argument doesn't even contain 15% because "other" covers resolutions such as 1900x1200, 1680x1050, 1440x900 and 1366x720. Thus, after running several polls across several forums it seems that about 3% of people ran 1600p and 1% ran Eyefinity or Surround.
That is already limiting the use of
one 6990 to practically none. Ask around of those 6990 users and most of them are running 1080p.
For a good gaming experience Vsync should be enabled. If not you will be subjected to tearing and so on. And oddly, it's mainly users of these 3 or 4 GPU set ups that can't even see the tearing.
Why is that? because they're spending most of their time messing around and not actually playing the games. When running multiple GPUs Vsync is absolutely crucial as it assists in synchronising the graphics processors in order for them to do the task of drawing opposing lines and pixels more seemlessly. Do you understand how multiple GPUs work?
SLI and Crossfire are nothing new. SLI was being used by 3DFX back in 1998 and even before. And, it was inevitably their downfall because they insisted on using it and all the while they were getting their butts kicked by Nvidia who were sensibly using
one GPU.
The reason was simple. It was mainstream, it was cheaper, and it worked. Adding more GPUs simply added headaches as you then had to ask the people responsible for coding the games to add support for it. And, just like now most of them can't be bothered.
If you still refuse to listen to sense, and insist on using SLI and Crossfire then at least admit the true reasons for it.
Because there isn't a single argument in its favour unless you are forced to use it (like Nvidia surround). At that point you subject yourself (like I have, and why I am now trying to sell my 295s) to all sorts of issues because the world doesn't revolve around you no matter how much money you spend.
That doesn't make me condescending, a troll or anything else. It simply makes me some one who is trying to talk some sense.
). From what I've read, adding another gpu increases your fps? Surely 50-60ish fps is enough?
