Poker tracker + playerview + 6 games = slow

[rivered]

I usually play 2 or 3 different sites at once. Now with playerview coming for UB and Stars as well I'm thinking about upgrading....but to what. I'm at 2ghz now and, depending on which sites, it's okay mostly but slow at times. Anyone out there at about 3.5ghz and playing 2 or 3 sites at once and multiple dbs on poker tracker at the same?
