hi, I am looking for a desktop that can use multiple monitors tgt (3 mons)

usually will be doing surfing, FB games, blu ray movies together

please quote without monitors, kb, mouse, speakers, and also minimize laginess between all 3 task in a go. (my old desktop currently, if loading FB game, my movie will start lagging for a awhile)

budget around RM2k? (not sure the price for this)
