I'm in the market to get a new PC to mainly edit HD video footage and was wondering if anyone can recommend a brand they like. I've had Dell and have been happy with them but I'm reading horror stories about their customer support and how it has gone way downhill. What PC company do you think has the best tech support?

Please don't suggest Apple... I'm a PC guy and want to stay on that platform. I'm also on a budget and comparable Macs are about twice as much as a PC. I'm even hearing stories about how their tech support has gotten worse.
