IMHO the best motherboard out there right now, for everyday use and OC, is the Gigabyte GA-K8NNXP. I say so because it does have an AGP lock, and unlike the Chaintech Zenith, you are able to adjust your RAM timings. I had the Abit KV8-Max3 also, but returned it. It had awsome bios adjustibility, voltage wise, but it just wouldn't clock very well with my Mushkin. Not sure how it does with other ram. My ATI video card also didn't like the overclocked speeds, and would crash in games unless it was at near stock settings. I figured, what's the point of having this motherboard if i can't use it mildly tweaked for gaming.
