Both those companies make motherboards, but I wouldn't personally buy one from either of them. Graphic card wise, yes, they're both very good. eVGA, XFX are probably the two premier video cards around. Both have incredibley high clock rates (depend on the version you get) and are proven. I have an eVGA and it works great, but if there was an XFX card cheaper than it's exact counterpart (eVGA), I would get the XFX. Whichever one is on sale, hehe.
