With windows 7 being released next year, should I just download the beta for a build in august/sept. or go with vista? I've read some stuff on windows 7 RC through the forums and mags like maximum pc and it sounds like the beta is fairly impressive. Not sure about compatibility issues and drivers, but I'm on the fence whether I should sink the extra 100$ for an os in to a better gpu or possibly dual montiors? I've looked for a similar thread elsewhere with no luck, so sorry if I'm beating a dead horse.
