Based on your list Im going to make a few suggestions. I dont know your budget but Im going to assume around $650, which for a desktop would be a midrange gaming computer. Ive personally used ASUS motherboards and have talked to people who have used ASUS laptops, so they are a good company.

This is an open box. Ive also used MSI and they are considered top notch in the DIY pc world.

Dont get caught up on the CPU speed too much, the ASUS one is quad core, while the MSI laptop is a dual core. I would suggest going with a quad core, its better for multitasking. You might noticed that the ASUS laptop only has 8Gb of memory, you can upgrade that (oddly it only supports up to 12Gb). DDR3 is cheap, 4Gb is about 30 bucks. The Newer AMD CPU's have an integrated graphics card thats inside the CPU itself (rather than offboard). In the reviews Ive read, they are generally much better than integrated graphics.
