My current system... Intel D845PESV mother board 2.4ghz P4 478 pinset 1GB ddr ram (2 512 sticks) 160gb primary HD 80gb secondary HD 2001(ish) Sound Blaster Sound card Nvidia Geforce6600 256mb DVD drive CD-RW drive all in a Antec PLUSveiw100AMG case I'd like to just upgrade the motherboard and processer. It seems like the trend today in to go dual core. Any suggestions? My main deal is games, seems Hitman blood money and some of the newer games are requiring 4ghz+. Do you just add the 2 processers together to get your new processing power? Thanks guys.
