A cheaper 4670K will be just as good for gaming.
It would be appropriate when paired with a GTX780 or better.
It is the graphics card that is most important for gaming.
60gb is too small for the os. Yes, it will fit, but many other files want to go on the "C" drive. Buy 120gb at least. That will hold the os and a handful of games.
With 240gb, perhaps you can defer or omit the hard drive entirely.
On ram, the intel cpus are not much affected by speed or timings. Think of the cas numbers as the overhead to get the speed started. Lower is better.
Look for a 8gb(2 x 4gb) kit of low profile DDR3 1.5v 1600 ram.
