My Dell XPS410 desktop, about 3.25 yrs old, Vista Home Premium.
Everything being relative, the machine feels slow now that I have the Studio14 laptop with the i5-520M CPU and 4 gigs of DDR2 DRAM. But the Studio14 is running Win7, which feels dumbed down in Music and Video, where I do a lot of editing, processing, etc.
So, the XPS410 is still my main machine for that work.
My friend just got a computer from Maingear, with a six core Intel processor, 12 gigs of DRAM, US$3500, mostly for crunching for various projects running BOINC software. I generally cycle about a year after him, which is cool. He really knows his stuff and I learn from him. So, that is where my next machine will probably come from. But, not for US$3500.
