Can you play Team Fortress 2 on a Asus G50VT-X5

You would be able to play Team Fortress 2 on this laptop with everything set to high.

This is a very high spec laptop with a DX10 9800GS 512MB GDDR3 top spec Nvidia graphics card.

Team Fortress 2 is a DX9 game so high settings will be no problem at all.

DX10 games like Crysis and GTA4 should run fine on medium details.
