this is probably a dumb question, but how does a media pc compare to good av equipment? By good, I mean about the £2k mark. I have a pc I could use as a media centre but I was going to go down the amp, dvd player etc route. this could save me a fair bit of money if I use my pc instead. It has a PCIE card (6600gt OC) so I can display HD content, but how would it sound compared to say, the yamaha 757se amp and denon 1920 dvd player?
