A lot of people seem to be missing that the AMD CPU linked isn't a CPU, its an APU, a CPU/GPU combo. That said, its not a very good one.
Theres a few things wrong with your build link. One, its on an old socket, FM1, when the A series APUs are on FM2. APUs rely HEAVILY on RAM speed, as its just a GPU core with the CPU, it uses the standard system memory, DDR3, which is much slower then most graphics cards GDDR5. You'll gain a good 15-20 FPS on just upgrading the RAM speed to 2133 or so. Unfortunately, I don't believe you can buy 2133 below 8GB, so I would go for at least 1866 in this Kingston HyperX stick.
You need to go FM2 to have better performance per dollar and upgrade possibilities, I would suggest the ASRock FM2A75 Pro4-M. For the APU, the FM2 version of what you have on that list is the A4-4000, but honestly both are absolute garbage chips and really not THAT much better then your laptop. Better, yes, but I honestly don't know if its enough to even bother spending the money on. I would suggest taking a step up and getting the A6-6400K, a nice middle ground between the bottom of the barrel (A4-4000) and the A-Series flagship, the A10-6800k.
EDIT POST: The tf.tv forum linking is absolute garbage, so here is the above APU list:
A4-4000: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113343 (dual core)
A6-6400k: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113335 (dual core)
A10-6800k: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113331 (quad core)
I would say look over the entire FM2 APU line to fine whats right for you. Theres a few quad-cores for cheap with decent GPUs on them, look them over and find what price is right for you.
