its not a bad choice, the build quality is also better (way better) than the previous line of acer laptops.

GeForce 8400G is barely okay though,you can play C&C3 with no problems, and most likely none with sc2 as well.. it would be better to get something with a 8600GT/GS in it. if im not mistaken the acer aspire 5920g has it for slightly more than 4k

you might wanna consider an Asus or a Dell though. both have good specs for the price range. i configured a inspiron 1520 with 8600gt for less than 4k before.
