Buying new hardware, like new graphics cards .. mother
boards and other stuff. It depends on the person and
what they want.
I really don't have too many bad habits ...

One is
computer hardware. I want my PCs to run fast and trouble
free. Hardware some times burns up or just stops working.
I have extra hardware just hanging around, just in case of
someting breaks. Extra memory sticks, graphic cards, hard
drives, mother boards, dvd drives ... and other stuff...
Bottom line,if you got extra $$$ I would upgrade to a
better graphics card, if the other hardware in your computer
can handle it.
Right now, I'm planning on getting a new hardware for
my main system. As soon as they release the AMD 64 X2
CPUs and new ATI 520 graphics cards. It should be a killer
gaming system when done ..
