a friend is looking to get a graphics card for his pc so that he can play some games, his pc is a dell e520 with vista and 3gb ram but only has onboard graphics. unfortunately he is on a budget and can only afford approx £75, ideally the new graphics card should have min 512mb and wouldnt need a connection from the psu (the psu is standard dell 305w one). i have not looked at to verify if it has a connection for a graphics card so for now i will assume it hasnt got one.I have had a look for one but to be honest i know nothing about graphics cards so please help me find him one
