and since it been happening for a long while now, it actually sound louder.. i mean before it has the sound but wasnt this loud. it also feels like its loosing power.. meaning it doesnt accelerate as normal as it suppose to.. its slow, sluggy, seem to struggle gaining speed and all that.. any other ideas?

could be all sorts of things - power steering pump, alternator, a/c compressor or a/c clutch, water pump, idler pulley, tensioner pulley... I would start with pulling the accessory drive belt, start the car, see if it is still there... don't run it long like this, as the alternator won't be charging without the belt, but it should only take a few seconds to determine if the noise is still there or not... while the belt is off, spin all pulleys by hand, see if any are rough or have lateral or vertical play...
RPM is normal if the car is cold...
