Re: Wanting to build a monster computer!!!!
You didn't say what you wanted this computer for. If you want this for video games, then yes, definitely get the 5870 ste picked out for you, its a monster of a card!! If you're a light gamer however, you may pick something less powerful and less expensive.
To utilize triple channel memory, you should get a 2 X 3GB kit = 6gb which is more than enough for most tasks. Depends what you want to do with the computer i guess. But keep in mind to use multiples of 3 for this board to utilize triple channel.
