as an answer to A, in MOST cases a 6950 would easily hold it up. If you're gonna do gaming, get two of them, but otherwise one will suffice. A note here: get the Asus DCII 2GB card. It has 4 DPs and runs cool and quiet
B) Three display port cables are about your only option as far as I know.
i'm on a semi budget, ~$2k for the custom system... and i still need to not piss the missus off, by going over that too much. squeezing for the 3 monitors, not sure i can squeeze another ~$300 for another card.
i'm goin with an ASUS P8Z68 Deluxe MB, 16G ram, probably an i5, maybe i7 (see another squeeze point... sigh)
i can put another one in the system in a few months... say 3 or so as i have a bday in there...
i really like the dp 4 outputs of your example... i was seeing 1 on the card i was looking at. Thanks very much for that!
or should i just go break my piggy bank and just suck it up? (please be kind to the piggy bank)
MB: ASUS P8Z68 Deluxe (i believe it supports up to 4, and i could probably get a third for birthday (card that is)
HD - going cheap here. i have several 500G Sata2's
Monitors - going with 3 of what you descried.
Video- going with 2 of what you described.
assume case, and fans etc, and processor fan etc.
question: to run 2-3 of these cards do i need an upgraded power supply. i don't buy cheap power supplies, but what sort of power requirement limitations am i looking at?
it's been a number of years since i bought myself a new desktop, and i'm trying to do it basically once.... spend the time up front, determining what I need, and then pulling the trigger, and NOT a week spent going crazy, rounding up the stuff i forgot....
I work at an educational institution, so i have full access to what i need for OS etc, and allowed per state contracts.
I can't see any way of getting around the "dead spot" in the split between an even number of monitors... which I could only assume why people use an odd number (3, particularly) - to allow the center as the 'main focus', with the additional two or four for sides, then possibly above and below (top and bottom.)
SO - considering you will *really* only have the side monitors for peripheral vision...
Perhaps think about using a single, higher quality, larger monitor for the center and two less costly and/or smaller monitors for the sides.
I have a mix of many types, including two 40" Panasonics to one PC... I think my next "gaming" solution will use either a 24" or 30" center screen, with two 20" or 24" side-monitors rotated 90-deg to match the height. (Though, that 27" ASUS on NewEgg don' look too bad)...
Eyefinity 'stretches' the view across all monitors; so if you're running 1600x1200 on all three, your effective res goes to 4800x1200; Depending on your FX settings, you will see a range in frame-rate with just a single card.
If you bump that up to a second card, the variation and maximum framerate will increase considerably (based on the GPU).
Though I would expect you may be able to get away with setting up your monitors with a single 6950x2GB by something like:
Your side monitors will only require half the pipe of your higher quality monitor, and thus *might* (I'd need to test it to be certain) perform as well as TWO 1600x1200 monitors (which I believe works fine with the 6950/6970)... and as I mentioned - you won't be "viewing" on the side monitors as it's almost entirely peripheral vision - you'll probably only be able to notice movement, unless you draw your eyes from the center screen (versus turning your view-point).
** Edit **
One more thing - if you're tight on physical desk space, you can also rotate the monitors 90-deg for a 3600 x 1600 "desktop" vs the (normal) 4800 x 1200.
does the variable monitor resolution effect the eye-finity? i think i was reading that they had to all be the same or were at least recommended...
the reason i ask related to gaming as i know the frame rate is important in the gaming, has been since i got hooked on Forsaken so very long ago.
i will be using this for business as well, as i herd databases and write software for a living... so the multi monitors are important very important for that... but the gaming is the only real 'stress' they'll be under.....
Unless you're absolutely wanting to run 3 monitors to play games, just stay with a single graphics card, and use the single monitor for gaming, while the extra two for work.
For desktop-ing, non-3d, the 6950 is over-kill.
