Radeon an geforce are the major and only graphic chipsets FOR GAMING that normally ppl take and are popular for gaming.
try to avoid ati as they have many driver etc probs,but if they give better bang for buck you MIGHT try them if their aren' that many probs.

cards are then made by companies like asus,ati etc using these chipsets i think.
For todays generatin card,asus shd be fine .
leadtek shd be fine
xfx is ok in india ,availbale many places
