Kent just got an upgrade but if not for that i'd say he had you beat every
day of the week (and twice on sunday)
but lol, what's your specs? You may be right we could use your machine as
the min specs maybe...
and btw my comp is kinda old, i think like 2 years maybe more... it's a P4
2.6GHZ w/ 1GB RAM so shrug.
