GUYS , the dude made a mistake lets not RUB IT IN TO HIM , what ever he got he spent good money on it , he must be dissapointed but nothing can be done about it now . so let him enjoy his card as it is .
even if its a weak card fajoo play with it for some time , and at a later stage sell it of ASAP u might loose some money but if u can manage to get a 4870 even in used go for it , the performance is stellar.
i know the feeling of geting something and not geting good performance from it .
but still hang in there .
