I would suggest you to get 8gig stick of ram, you cant have enough ram given Vista is quiet ram intensive (as I found out...) as for video card reference cooler is pretty loud, i think other brand might have a non reference cooler (mine 4850 came with a Zalman fan, much cooler and quieter...) (i have to read up on the memory bits coz i stop reading the latest and greatest from both Intel & AMD for a good few months already lol...) if you gonna crossfire/sli path, i would suggest you get a better case to fit in the video card and at least a decent 600 watt PSU... 2 x 4870 will give you alot of BANG for the bucks atm, performance wise it beats nVidia in some games...
