She's absolutely right. Believe it or not it gets even hotter than an AMD! If I were you, I'd save up a bit and try to upgrade. The most you'd probably get out of that chip may be 15% or so, but you wouldn't hardly notice the difference. Yet you'd have to sink a bit of money into cooling it.
interesting you say this because I have one of these chips here on a PC chips board (no I didnt pay money for it ) and have a crappy no name heat seat and fan on it and showing no signs of being hot, mind you I wouldn't overclock it in my wildest dreams.
I would go a cheap duron like suggested above, it will leave the Cyix for dead and have far more OC potential.
