I couldn't get driver forced SLI anti-aliasing to work after installing RTSS when it came with precision X. I ended up reinstalling windows over my confusion with RTSS messing up my driver settings. You seem like you are not so noobie for a noobie- can you explain me what's the advantage to the 64-bit version? I switched to precisionx and everything seems groovy, but I was going to switch back when the new AB beta came out, now I lost track and seem fine with where I'm at.
