I dunno I bought this machine specifically for this arcade cab - was told it would do great... its P4, 2.8 ghz, 160HD, 1 gig ram.. Can't really afford another PC ( wife would KILL me - no really, she would !!!) so I will step down to a 128MB card and see if I can get it to work (sigh) I will place an order from newegg today and let you guys know the results. Once again thanks for taking the time to help me here - I know I am a PITA and I really appreciate you guys helping me.
