    Hi all,
    It's been a while since posting here but I have a question regarding multi monitors in SLi. I know that I can't run 2 monitors while in SLi mode.

    My current PC has a 7950GX2 and a cheapo ati card for the second monitor.

    I want to upgrade soon to 2x N280 GTXs, if I were to get a tri SLi board (such as XFX MB-N780-ISH9) could I hook up the 2 280s and use the 7950GX2 in the 3rd slot to run my second monitor?


    Thank you in advance


    Dave

    I'd suggest you to buy a whole new computer because you're going to bottleneck your graphics with an older CPU.

    On your problem I have no idea, but I think it should work.

    I was looking at getting a Q9450 with 4Gb OCZ PC9200.


    I know when I built my current computer there was an issue with multiple nvidia cards in a multi mon setup. Hence why I have an ati card for the second monitor, but I'd rather not get rid of the GX2 just yet

    We found a 3GHz quad core was bottlenecking a single GTX 280 in some cases, so, unless you're running a 24" or 30" monitor SLI won't help.

    I'm going to be getting a 26" (1920x1200) with it. The second monitor will be a 20" (1680x1050)


    I could *just* stretch my budget to a QX9650. Would this be worth it?


    Thank you

    Overclock the nuts off the Q9450 to be honest - buy a good 4GB kit of memory and a good heatsink and have some fun. It'll easily give you 3+GHz.

    I'd say see how you go with one, but also bear in mind that mixing pre-8 series and post may have driver conflicts. I'm running an 8800 GT and 8600 GTS in this PC and it's a *little* funny with 3 monitors.

    Cooling isn't going to be an issue, I'm running water cooled as will all the gfx cards. As a result I'll also be running aquacomputers 9x120mm radiator outside the case, possibly with 1 or 2 temp controlled fans.

    Would it be worth flogging the 7950 and buying a mid range ati card instead then?

    With an Nvidia card in addition? That's asking for more trouble :p

    See how you get on with the GTX 280 and 79GX2, but what I'm saying is don't grow too attached to the latter..

    I know that was the solution when I first built this rig. I assumed it was going to be the same situation.

    I suppose if the GX2 doesn't work I could always get a 260GTX :naughty:

    Nvidia never supported the 7950GX2 - it was an e-peen product against ATI.

    Uh, yea a GTX 260 just to power a second monitor. I feel sorry for you power bill ha! :p

    Why not just use the 2 GTX 280s in SLI for gaming, then disable SLI and use the extra monitor in every other situation? Tbh most games won't stretch a single GTX 280 so even if it does support dual monitors (Sup Com for example) you have more than enough horsepower for both.

    Does SLi automatically enable/disable itself when in games or do you have to go through the driver application to do it?

    It's non-automatic. You have to right click desktop - Nvidia control panel..

    That's going to be irritating. I'll try it out with the GX2 for a while and see if I can get it working.

    One more question, 2x2Gb or 4x1Gb?
