Finding a laptop computer under $400 isn't generally a hard thing to do these days. Most of the laptops are either based upon AMD's APU processors or the Intel Pentium processors. While these provide enough performance for most people they still struggle at times. If you want a faster PC but don't want to spend a lot, then the Lenovo G570 from NewEgg for just $380 might be something to look at. It comes equipped with an Intel Core i3-2370M dual core processor that gives it a nice bit of performance over many other systems in this price range. Other features include 4GB DDR3 memory, 320GB hard drive, DVD burner, 15.6-inch display, 802.11b/g/n wireless and Windows 7 Home Premium.
