Can this computer run top quality games like Crysis/Fallout?

Now that is a nice set up and should be fine but due to your low clocking speeds on your main processor you might have a few problems with freezes and lag. But it may not, The graphics card card you have is fine and 8gb of ram will do great with this. Now i have a laptop with an I3 and only 4gb of ram has me running preaty intensive games. I advise getting a decent mother board witch will accept either an amd phenom II if you have a desktop or an AMD Phenom™ II N970 witch has realy good performance for a laptop, now the desktop i advise AMD Phenom II 1090T. This will bring amazing perfomance. Now i went into AMD and not intell because AMD is the better choice for graphics and it is a lil cheaper than an intel with the same performance.If you want to stick with intel then id get an I5 because it can boost its clocking speed when needed. Now If you want to go all out and spend tons of money on a rig I would look at getting a cell processor just because of its computing power, however last i checked it would run you in the 5-8 thousand range so yea.
