I did some searching into Emulators for the Xbox 360 (getting a bit tired of being forced to play my favorite games on hardware less powerful than the integrated graphics in a non-gaming laptop), and inspired by a friend of mine who was playing Super Smash Bros Brawl on his PC at 60 FPS, 1080p. I found a few sites that seemed to be sorta legit, in that at least they actually give me downloads instead of redirecting me to survey sites. There are also some youtube videos (with decent ratings) showing working emulators (at least of GTA V), but then again those aren't exactly difficult to fake.

However, upon some searching as to the legitimacy of Xbox 360 emulators, I find plenty of threads of people saying that Hardware hasn't reached the point of being able to emulate the hardware.
Doing some searching though, and the closest thing I could find to an equivalent GPU for benchmarks is a 7900/7800 GTX, to which my 660 ti appears to be more than 15 times as powerful. And with a gaming laptop being able to emulate Wii hardware, it doesn't seem like we're too far off from a desktop gaming PC being able to handle last gen's tech specs, barring any programming/architecture differences that need to be worked through.
I'm obviously missing a part of the picture here, could somebody fill me in on what's really up?
