I have a asus motherboard it is M5A78L-M/USB3. I was woundering is the MSI R9 390 GAMING 8G gpu is compatible with it. if It isn't is there a motherboard that is that has a micro atx lay out with a 240 pin ddr3 ram slots and that fits fx 8150 cpu? also could I use a second psu for second port pci-e power port on gpu
