Some Questions,

[Boss]

About the RAM, no. DDR2 uses a different slot type than does DDR. DDR2 is 240 pin slots, DDR is 184 pin.
This set is decent:

As for the power supply, that part's easy. Gimme a mobo model #, and I'll tell you.

That video card will not work. Your motherboard, if it doesn't support DDR2, will not support PCI-e. Try this one:

Just go play the game and have fun dammit.

all in all the conclusion is that disco doesn't need antagonist factions, it doesn't need phantoms, it doesn't need nomads, it doesn't need coalition and it doesn't need many other things, no AIs, the game is hijacked by morons to confuse the game with their dickwaving generic competition games mixed up with troll-of-the-day.
