recent video cards require atleast 400 watts, 26amps, and 6 pin pcie power supply connector. may converter naman sa 6 pin power supply plug kaya no problem as long as decent yung power supply. a lower psu could also take punishment but it could cause lag sa power peak demand.
I'm actualy runnung a xfx 9600gt extreme ed. on a 385watts 18amp.
a Brand new Galaxy 9800GT 512mb-1gb * 4,800 -5,500php looks scary enough if you ask me.
or a 2nd hand 9800GTX * 6000php looks scary as a GTX295.
btw ano po ba size monitor mo?
