Ignore the Laptop. Get a PC - You can upgrade easier (and cheaper), it will last longer and accomodate more future-proof components, as well as doing more at faster speeds with better performance. My comparatively old PC is a midi-tower, not even a dedicated gaming rig and yet it has specs that equal the new XBox One!
Dragon Age and Dragon Age: Awakenings are fantastic. I've played both about seven times, now!
DA2, not so popular, although fans of Mass Effect seem to get on with it well enough. Both Bioware, so similar interfaces in DA2.
However, DA is of similar ilk to Baldur's Gate, ie a combination of action/adventure and strategy roleplay, so there's lots of pointing and clicking at icons, tactics sets, opponents and things, kinda like Warcraft. Real Mouse & Keyboard stuff. This means it fuggin' SUCKS on a console.
