Hi I have purchased 3 x asus vg248qe 144 hertz monitors along with a gfx 760 card.I am under the impression i will need a display port to dvi dual link adaptor to enable 3d surround.
Most that i have seen are extremely pricey .I was wondering if anyone has links to some fairly cheap ones that will work for me.

Personally I use the BizLink DP to DVI Dual Link adaptor, when I purchased this when the 5870 was released it was touching on £100 inc delivery, with a bit of searching around I see these can be picked up for as little as £30-40 (excluding delivery), personally I would say these are now cheap.
What do you call cheap and what country are looking to purchase in?

Could I bypass the need for an adaptor and use a second gfx 760 card for the 3rd dvi?
It doesn't give me the option on nvidias page to run that particular card in sli but it does for older cards....

Ok so a second video card does solve the need for the adapter to achieve 3d surround.
That said It appears to also give me a much less score on 3d mark especially on the one game/bench it drops from 193 000 to 56 000 when sli is enabled across one monitor vs when having the sli enabled across 3 monitors [2 of the monitors are blanked out during test so essentially running on 1 monitor as well]].
So basically sli enabled with 1 display on one video card = 193 000 on 3dmark
Sli enabled 3 monitors across 2 video cards [while displaying 3dmark tests on 1 monitor]= 56 000 on 3dmark.
The other tests are not a dramatic of an increase/decrease but they still have a lower score with three monitors enabled in sli across 2 video cards.
That said would an adapter help out with this issue since it would allow all three monitors to work off 1 card and allow sli to work properly.?

When using SLI or Crossfire it is recommended to ensure that the application you are attempting to run has a SLI/Crossfire profile in the gpu drivers.
without a profile, applications will often perform slower with 2 cards than a single card, it is possible to take a working profile and apply this to a application with unknown profiles, sometimes this works, sometimes not.
