ok so this is the thing, i want 3 monitors, i currently have 2.
i have this motherboard : Asus crosshair formula iv
but i have this main video card : EVGA GTX 470
problem is that i had this video card on my first gaming rig, i bought this mobo and completely didnt see that it doesnt support
um... whatever its called when you join 2 nvidia cards for joint power (crossfire or the other one ) lol, only supports the ATI cards linkage function (forget the name!)
both my monitors are plugged into the GTX 470.
as it stands, i dont want to game on all monitors, i just want to be able to extend my desktop to all three monitors without any special ACTIVE display adapter or anything like that.
my question is, if i buy a CHEAP nvidia card so i can plug in the 3rd monitor,
can i then use three monitors right out the gate? and share resources between all of them, or do i still need something else altogether?
does this mean that it shared the load with the 2nd less powerful card or it makes it number one?
or whatever phys x does, itll give to the second allowing the 1st to still be number one card with more power to spend?
It will probably set the secondary card using the auto-select process. It should say right underneath the drop-down. You can manually select the second card, but I don't think you'll have to.
It will continue to leave your 470 as the primary either way. With the 430 selected as the PhysX card, you offload PhysX processing to the 430 so the 470 can perform even better than if you just used the 470 alone with a PhysX-enabled game.
