Can you believe..I still  have not yet solved that.
one the 680i is kind of out of stock in all affordable shops around her!
I finally saw one 780i: XFX 780i 3 way - SLI  it's kind of expensive but it's maybe available in a week. Not exactly my needs but will fullfil all the needs and left some .. ;)
I have read the 'marque' post about  using a High Definition TV as a monitor! It's a 32 " samsung w/5000 contrast and HDMI connectors.
So I looked up here, and those Tv are super less expensive than a regular monitor about 27 " from same samsung, and 3000 contrasrt.
So I asked her and she told me she uses it for Cs, C+CC++ and many others applications (Vue,Poser etc..) i got crazy! It's totally fantastic to have such big size (mostly when Nvidia has not yet realease a driver that enables to have more than one monitor while in SLI Mode.)
Those Samsung 37" and 40" HD TV  are with 15000 contrast 1.8ms and loudspeakers in it as well 2 HDMI connectors as well VGA. For about 20%,30% less than a 27" monitor from same maker!

Anyone here! Should you use it instead of your regular monitor?

I'm having problems for the shop to take back the 650i board I got here (they say it's 30 days old now) but also I brought with then a Samsung 27"  - 15 times more expensive tahn the board and it's only 1 week old. So I think maybe worth to send back the Monitor and buy a HD tv instead (save some money here ) I can use the board in my son's computer, he does not have a SLi but a PCI-X 16X card - normal but it's ATI not Nvidia...)
