well, I have a athlonXP 1800+, 512mb PC-2100, but sometimes I get kinda frustrated with it. It is mainly fast, but I have issues every once in a while, even though they are probably not speed related.
I kinda wish I had a faster burner though, my 4x is just getting way to darn slow. My only problem is that it just won't break. I have had it for 3 years and burned over 500 cd's on it but nothing I do will make it die. as soon as it goes, I can get a new lite-on 40x, but until then.... grrrrr
