I may be new to some of this, but I've buitd a few machines in my time.
At this stage, I dont see how a wide x16 card can possibly PHYSICALLY fit in a x8 slot. Perhaps some cards can (hence the statement that x16 work in an x8 slot), but not the cheaper ones readily available. They would need two notches (to flank the x8 connector) - but they only have one notch - so it cant possibly fit.
The only we to do this is to use a x16-to-x8 riser/extender ( which is why, I assume, they make them!)
If I am wrong, please enlighten me.
If I am right, this is getting way too messy again and I am back to:
- give it up on 3 monitors; and stick with two monitors and the existing OEM 5670.
-invest in a replacement x16 card with DP
, ie DP/DVI/HDMI, and in an active DP adaptor
