Yeah, a monitor is the only thing I'd (possibly) be willing to spend that much on. A few years back I spent over $1000 on a 21" CRT, but right now the only monitor I'd consider is a 19" LCD (because 20" ones have too high a resolution), and you can get them for $460-500ish.
Right now the most I'd spend on a CPU or video card is $300-400 each, absolute maximum. Unless I could spend $800 on some CPU or video card that dosen't exist yet. Like magically buy a 7Ghz P6 or something from the future

And even then, only if I could also magically get drivers for it from the future.
