My brother has a laptop with a dual core amd processor and a hd 4250 mobility series gpu. He wanted to upgrade but was not sure which was better. He could get this http://www.villageinstruments.com/tiki-index.php?page=S... with a 7750(The resolution is only 1336 by 768) to power his laptop but that would be paying 300 dollars for a 100 dollar graphics card. The other option would be to get a whole new computer. Which one is better to go with?
