So I put together an old P4 rig for my son that has a P4 2.4ghz cpu and a HD2400 PCI-E video card in it. It has 2 gb of ram and as far as multi tasking and surfing the web, it does that fine, as well as playing back HD video, but when it comes to pretty much any newer game, well, it sucks. Would putting a $50 video card into it actually do any good or is the P4 just way too crippling?
