After playing the game for a couple of hours, I really have come to like the Elika-saves. Falling from a ledge and having to replay an entire section is not fun or challenging, it's boring and annoying. Elika keeps the game moving forward, which is just what I want.

I don't know much about how the amd's stack up, so I can't help you there.
Regardless, with a good video card, 2 GB of ram, and a dual core you should be able to play most games on decent settings. You can also plug in your 360 controller for most games as well if you don't like keyboard/mouse. I bought one just for that purpose! Good luck!
