Well I was looking at the nf3 250 S754 boards, most likely the MSI Neo or asus k8n-e deluxe. I remember reading that all the S939 boards featured working agp/pci locks (despite that fact that, as you said, it's not mentioned anywhere)
So I have to look around to make sure either of those 2 boards has a working lock?
If I plan to OC I want a working agp/pci lock right?
