I realize this is an old computer but I'm trying to rig something together for my mother to use. Anyway, this has an Intel Celeron D 336, 2800MHz cpu. Graphics-wise it has an Intel 82945G Express chipset. It has 2GB of DDR2 (4x512MB) of memory. There is a 40GB pata hard drive. I installed Windows 7. Tell you the truth but this is probably good enough for her needs but it cannot even stream online video properly - they are way too choppy. I am wondering what CPUs the motherboard can support? Secondly, can anyone recommend overclocking either the CPU and/or the onboard Intel graphics? And if so, what kind of experience did you have? Thanks for your time.
