But.... i want keep my casing and drives, only replacing the motherboard. I currently own a Gateway 509GE which houses a Intel Augsburg D915GAG motherboard. The Powersupply is a HP-P3087F3 300W. I'm looking to get an Intel DP35DPM motherboard, and put an Intel Core 2 Duo E6750 processor. With my current power-supply and casing, would i be able to house this motherboard and power it efficiently. I will use it for nothing more than mid-core gaming(maybe running games like oblivion at low-mid settings), and not very power needy processes.. basically what i want is to run what ever i run now.. faster. thanks for any feedback
