Hi Joshua,
I build gaming Computers for a living. Manufacturer's will try to tell you
that integrated graphics(well the X3000-X3100 Intel series, as well as
others) can handle game play. This may be true for games built for DX8(games
from 2000-2003) but games built for DX9 or DX10, are going to crush
integrated graphics.
Get a discrete PCI-Express Video card with 256MB of Ram or better(Get a
6800GT or better, for Nvidia, and an X800 or X1600 or better for ATI(stay
away from the X1200-X1400 series)
Happy Gaming,
JC
