Well your not going to be able to win then if you buy a crapo cheapo card, that probably won't even support EQ2. To add, one of the main features to EQ2 in my opinion, is that it has amazing graphics. Why sell yourself short buying a vid card that barely makes it, and have to play on EXTREME performance, which means, no NPCs or other people or even water look nice.
If you want to save cash, but still keep the game at high performance, which to me is still just breathtaking graphics, then go to your local best buy, and shell out the 150 bucks like I did man. If your card has to be PCI slot only like mine was since I have a crap computer then make sure you go for an nVidia due to their FX series being better then the Radeon equvialent.
=) Follow my words friend, and you will not be disappointed.
