Defintely get dual channel, helps with memory bandwith
. hmm looks ok. 1600 dollars isnt that bad, you think 60GB's will be big enough?
For bumping up the speed of your hdd, it will help with loading games, and starting up windows, i think its a good investment.
But for gaming, i would recommend an AMD 64 or Turion as a processor. 2.0Ghz-2.4Ghz speed.
