Ouch Paul, still on 775 and DDR2? My next pc will have 4GB of DDR3 dual channel RAM, with the motherboard being a cheap (but still nice) MSI Socket FM2+ and an AMD dual core APU, all housed inside a BitFenix Phenom, cheap but will be pretty powerful for the money and when I watercool the CPU and move up to Intel CPU's, I'll have one hell of a PC in a very small footprint!
