Instead, use the money towards something that you'll actually notice and appreciate on a daily basis. If you're a gamer, get a faster video card or buy more games. Get an SSD, or a bigger one. Get a bigger, better monitor (or a second monitor). Upgrade your peripherals - get a nicer mouse, keyboard, speakers, headphones, whatever...
Or just buy more beer
I would like to second the beer idea... you'd be surprised how much difference a couple of good beers will make for your overall computing experience. Just remember that as with anything else, proper cooling is essential.
Unless you're doing some really memory-intensive work you are better off spending the money on something like a video card, an SSD, a monitor... or beer.
