For the same price as a GTX460 you can get a GTX650 that will destroy it.
Besides it all depends on your usage, if you want just mainstream gaming/browsing the first is better.
You appear not to have noticed, but the first one has a GTX660.
*Hands down, the FIRST ONE. It's not even close.
It sounds like these are used?
**Also, for the second one I see an OSX installation on a non-Apple computer. That's illegal.
