i think is better to buy a gforce 6600GT graphic card. DO not buy a cheap graphic card cuz i had tried before, i had brought a gforce 6200tc and it works like ****!! even it a 256mb graphic card wit pci express perfromance... i think it better to spend more money to buy a good graphic card than a cheap one. And i will said tat if u are to buy a graphic card, pls buy a AGP graphic card than a pci express card.Because Pic express is much more slower than AGP card because pci use system memory and than conver to graphic card memory but APG is all use of it own memory at all times.
