How fast is your computer?

[TobDog]

I multi-table and recently have noticed that my home computer has some lag when having multiple tables open, I have noticed it more after I have been using 2 monitors with my notebook(which is faster than my home computer). I was wondering what you would(or currently) use as a minimum for a new purchase of computer? Currently I have a Dell Inspiron 600m(pentium M) notebook, that seems to be quick enough even with a monitor pluged into it to make multiple monitors. I have a celeron 2.4 as my home pc but within a few months will probably be purchasing a new one. Any suggestions, or what is more important( I know RAM is very important, but how much do I need to do between 4-8 tables, itunes, radio, pokertracker, etc.

Thanks
