I have an old Athlon 5200+ kicking around somewhere. On games like Oblivion it struggled even on the lowest settings. The Athlon 62 x2 line of CPUs is over 7 years old. They were pretty decent in their day, but you can't expect them to run much from the last few years at playable frame rates. If it is a choice between those two cpus or nothing, then get the athlon. However if you let us know your budget and if you need a monitor, keyboard, windows ect then maybe we could let you know of other options.
