Looks pretty decent, except it uses the A8 series AMD processor, which has built in graphics that score pretty low. You're gonna have a hard time playing any serious games like Battlefield 4 etc with the A8 graphics unless only running on low settings, so you should factor in the money for a new GPU as well. You may have to upgrade the power supply to get a better GPU though.

If this is the price for getting it new, it's not too bad but you won't be able to play anything on high settings, especially demanding games like Skyrim. The best way by far is to build it yourself if you have the ability to do so.

Awesome

Better yet, get the specs for the games you want to play. Then you can decide if the hardware is up to snuff:
Skyrim wants,
-Windows 7/Vista/XP PC (32 or 64 bit)
-Quad-core Intel or AMD CPU processor
-4GB System RAM
-6GB free HDD (Hard disk drive) space
-DirectX 9.0c compatible NVIDIA or AMD ATI video card with 1GB of RAM: Nvidia GeForce GTX 260 or higher; ATI Radeon HD 4890 or higher
-DirectX compatible sound card
-Internet access for Steam activation
