My buddy had an XPS. After a year of a veritable driver hell, trying all sorts of things to get it working, he had to replace the video card, which was a $300+ part.
I've got two dells here. After a random MB death followed by spending $140 to get a new MB that wasn't even the same model, it works alright. The other one had horrible compatability problems with the Audigy.
I've lost all faith in the desktop PC market. Seriously. And those 'Build vs. Buy' articles in PC Mag piss me off. Like there's any fucking competition. And those people who are like 'For five hundred bucks I can just get a Dell that has tech support and saves me time and is the same speed as what I could build' piss me off too. Because they obviously haven't checked prices anywhere. Five hundred easily gets you a socket 939 AMD 64, a gig of RAM, a big hard drive, a dvd burner, a cheap case and PSU, and X300 or so graphics. Dell gives you a Celeron with 256mb and a cd-rom. And seriously, who makes a decision 'Should I build or buy my next PC?'. It's like saying 'Hey, should I take this wad of 20s and light it on fire?'. People don't make that decision. If they can build, they build. If they don't have the know-how, they buy. Plain and simple. Building is ALWAYS a better deal.
People who spend four digit sums on desktops (excluding peripherals) piss me off too. It's one thing to get better the more you spend, but $1,000 will net you an entry level dual core AMD proc, a decent S939 mobo, a 6600 or 6800 or X800 midrange card, a gig or two of RAM, a 120-250gb sata drive, dvd burner, generic case, and a solid but inexpensive PSU. Anything above is horribly diminishing returns.
