Computer Build - Components?

looks like a great system dude, except for the power supply which is your most important component. i would get a good brand name one from ultra, thermaltake, or antec if you want to save some money do it elsewhere you need a good power supply. this almost like the system i want except i want 8 gb of ram and an antec 750 watt tru power power supply. i'll bet it will be fast. i have the quad core q9300 and 4 gb of ddr 2 800mhz ram and vista 64 right now and it is at least 20 times faster than my old xp3200 computer was. lol good luck :oP
