Hey! My brother has an HP Pavilion s3307c and he wants to upgrade it to a better specification, and lately we've been talking about graphics cards and if it is possible to fit one in this HP machine. So the question I'm asking here is, can this machine fit a graphics card and if so which could it fit the best ? The motherboard has an PCIe 16 slot for graphics cards so I'm asking if It is possible to fit one in there? Also we've thought of putting something like a geforce 210 in there.
