The hardware itself really isn't worth $600, but thats because its an envy model line. They are usually built a little better and have better speakers and etc type stuff which adds to the price.
It will easily play those games and quite a few more. It does have integrated graphics though.
You did good to upgrade to 8GB of ram, since if you have 2 matching sticks of ram, it will run in dual channel effectively doubling memory bandwidth (about 10-15% overall system performance boost, but it makes a HUGE difference in performance of integrated graphics)
Though you likely could have bought the 8GB of ram separate from the laptop for cheaper.
With dual channel memory your graphics are similar performance to http://www.notebookcheck.net/...631.0.html (there are a few game benchmarks, you can play quite a few games on low settings).
As for emulators, they are completely different from pc gaming. Pc gaming heavily relies on your graphics for performance.
Emulators require lots of cpu cycles, meaning you need a very fast cpu. Most emulators only use 1-2 cores, so more cores really doesn't help speed much. Meaning the performance comes from the clock speed and ipc performance of the cores.
amd cpus have terrible pc performance unfortunately, so they are not good for emulation.
like even if your cpu was turboed to 3.1ghz (which it probably won't go above 2.8-2.9ghz on turbo), it wouldnt even be equal to a 1.6ghz i3 or something in emulation.
Now you should be able to easily play ps1/n64/DS and probably psp with out much trouble at all (and ofc earlier systems). But ps2 and gc you likely won't get full speed in all games. You can probably get a good handful of games at good speed or even full speed, but there will be a lot you can't.
Wii is definitely out of the question, as for that you need a desktop core i5/i7.
