Guys, I made some changes in my rig, i sold my hd5870 and my old mobo ga ds4x58. Bought 2 GTX460 gigabyte1gb OC and a new mobo Asus p6x58d premium. So here is my question im planning to get a 1000w PSU and im wondering if adding my 9600gt asus for phyxs will be a nice idea? i havent installed yet cuz im running my 700w psu and im afraid to overload it. I can sell it and save some bucks for my new psu or ,will increase my performance if I keep it?
