I wish i had asked them to change my card now, i just cancelled it and re-ordered the card i wanted to change to. I only ordered the first card cause it showed in stock but when i rang the next day they said it was never in stock and was sold out instantly but the page was lagging behind so i just cancelled that card and ordered the one i actually wanted. Ah well ya never know, it might be a blessing in disguise if the ATI card is any good.
