MSI Geforce FX5600 256mb ram
512 ram
with an soon to be ISDN connection (BT being the idiots they are dont want to let me have broadband thats the price u play living in the glourius countryside sigh) so my connection will be 128kps
i've got the guts for the game in my system but i want to know if i'm gonna be playged by LAG problems which i dipise
