Got a new nice gaming rig this summer (8800GTS 320MB) but still didn't buy FSX. It's seriously not worth it. If you bought FS for the graphics, you might as well try a high-tech raytracing sim (I'm sure there are a few out there), but if you're more for the practical, aviation want-to-fly side of thing, FS9 is enough.
The real full motion flight sims that pilots use to train barely have scenery

That makes 1 Vista, 1 XP desktop, 2 XP laptops (one communal, one dad), 2 Fedora 6 servers (Web+Mail), 1 being converted into a Fedora 8 file server... so technically it's really just 3 usuable computers
