Personal I'll think a P3 is just fine, and if you want a little more speed for say a little gaming, try adding ram or go to a P4. I think that that would run almost anything. Why this obsession with speed? I don't get it. I have run a P3 for a while and if it wasn't for me working to be a pilot, and hence needing a flight sim, I would never wish to upgrade.

P3 mate...you havin a laugh.....its fine for powering up and down the computer. And 4GB high end ram would seriously bottleneck/strain a PC3. Not good enough for todays games mate.

I am going to have to eat this one. That was a total blunder, when I saw my comment after I had read your answer I thought, I can't believe I wrote that what was I thinking, play modern games on a P3 no way. Thanks for the correction, if you want to do any serious gaming get a P4, a P3 will do general low level work.
