I just bought a motherboard (ASUS P5N7A-VM LGA 775 NVIDIA GeForce 9300/nForce 730i HDMI Micro ATX Intel Motherboard) that has NVIDIA GeForce 9300 on board video. I have a PCI-E Geforce 7950 GT 256 Meg in my old computer. I can't find anywhere that says how much video memory the 9300 has. Does it share the memory with the DDR in the DIMM slots? Being that my 7950 GT is a couple years old, is the on-board 9300 superior to the older 7950 GT? If so I can disabled the on board and use the 7950 GT. Any advise or observations would appreciated.
