We don't know wether the X1950XT-X or 7950GX2 is the fastest of the two yet, as we have only seen one set of benchmarks so far. Those benchmarks, however, have the X1950XT-X pretty much spanking the 7950GX2 (I use the term spanking as the 7950GX2 is basically two 7900GTs in SLi, and a single card besting that so soon would be quite a feat of engineering.)
As for the choice of monitor, Bilenea is generally regarded as a good brand as far as I am aware. Personally I would go for Acer, Hyundai, Viewsonic, LG etc. for mid-range panels but I've never heard anything bad about Bilinea at all.
