Advice needed on hardware changes

Hey Tech Heads,I'm up for some hardware changes and looking for advice. I am primarily interested in upgrade since I already have the following:Athlon +1800 XP (getting old), 768 MEGS DDR RAM, and a Sound Blaster Live (getting older)I would like to upgrade my video which is an Nvidia GeForce 3 with 64 MEGS Ram and grab a new monitor, possibly flat screen, liquid plasma, or liquid crystyl.Then there is the question as what to do with the old video card and old monitor. I thought about going dual AGP for multi-monitor but then again not necessarily my cup of tea.OK, any serious recommendations? My time frame is not now and I am satisfied tweaking to grab the frames I desire in 2004. 2002 isn't a real consideration although the nes PSS 330/340 are robing some serious frames.Thanks in advance
