[stackingboxes]

Hi,

I normally 8 table, and have PT + PAHUD running. My database has around 1 million hands. I have the biggest problem with FTP, after playing for 20 min, the computer lags like crazy. (no pun intended)

My compute specs are:

Athlon 64 x2 4200+
2 gb ram
prob [censored] intergrated ATI video card.
Western Digital standard 120gb HD


of these specs, which one do I need to upgrade to get better performance? thx!
