I think if Vista was the culprit he would see crappy frames in singleplayer too.  So it looks like it could be the server you are on or maybe a network driver issue and lastly a net connection problem.  Strange though that when it comes down to it, you had the same issue with the old pc and now with your supercomputer.  Now i need to know if you play any other games online and if you do, how do they play?  Since youve had two computers and both have had the same problem when you play online..that leads me to think you have a broadband issue.  I would do some speed tests and see what you come up with (www.speedguide.net) since you may not notice too much of a hit when just surfing or IMing.  This may also be dependent on when you play, test your connection at different times during the day, then test when you hop on to play.  Do this for a couple days and see what results you get.  Your connection may be getting smashed by users around the time you play.
