That's great!

Basically, I've bought a new computer just so my wife and I can play this game and the last step in the process is adding an aftermarket video card (the new box came with Intel integrated graphics). My previous computer was from the Athlon XP days with an old GeForce FX board and had recently blown its capacitors, so it was begging for a replacement. Problem is, I've been out of touch with what's available for so long, I have mistrusted my own judgement, but it looks like I'm probably looking in all the right directions.

Thanks for the reply!
