No you're NOT!
You vacuumed off that northbridge heat sink like, what, six years ago?! That thing is ancient.
I was just looking at monitor prices on Amazon today (they had one on sale), and I was amazed at how inexpensive they've become. I bought a 20" monitor a few years back for, I forget, about $250 or so and thought it was a stellar deal. Now, they have 24" monitors for just over $100. If you'd like a larger monitor, you might want to check them out again.
