Can this computer run left 4 dead?

it is a T3516 desktop PC with an ATI Radeon Xpress 200 Series graphics card. it has windows XP home edition. 3.20GHz, 533 MHz FSB, and 512KB L2 Cache. it also has 2GB of RAM. i know about systemrequirementslab.com but i failed only at my video card and i want to make sure that it isnt TOO major in the turnout of my gaming experience. thanks in advance.
