Hello Guys, i need some help to upgrade my sister's computer which doesn't have a good hardware !! PROCESSOR : Intel CoreTM 2 CPU 6420 2.13GHZ GRAPHICS CARD: Nvidia Geforce 9400 GT Also it had 4gb of RAM... So i figured out that this computer needs for sure a new processor and a new graphics card ... So can you suggest a new processor and a new graphics card ?? I have about 700 Euros to spend , and I need to make a new good machine ... Waiting for your replies !!
