Is my CPU and graphics card good enough to play dungeons and dragons online?

My graphics card is Intel(R) 82945G Express Chipset Family and my CPU is Intel(R) Celeron(R) CPU 420 @ 1.60GHz, 1600 Mhz, 1core(S), 1 Logical Processor(s) I just want to know if i could run this perfectly without it lagging or my computer crashing. Oh and do i need a 64 bit or will a 32 bit work just fine?
