ok well thanks. Both computers are quite old. Tomorrow i want to buy an other with a i7 4770 CPU and more power for the watts. My socket is still 775. I am experimenting a with the older computers. I probably also want to buy the geforce 660 ti, which is as i heard a reliable and cheap graphic card. Not as good as the 700 series but affordable. i don't know how to close this thread. Does the moderator does this?? Thanks alexoiu.
