New Gaming PC for my son - Please review specs

My son places games like LoL and Skyrim (all online). He's needing something that will get him a good FPS and hopefully last a few years or more. Here is what I have come up with.

AMD FX-6100 3.3GHz
MSI 970A-G46 AM3+ AMD 970
G.Skill 8GB DDR3 1600
Cooler Master extreme 500W PSU
Samsung 500GB 7200RPM HD
EVGA 01G-P3-1561-AR GeForce GTX 560 Ti Free Performance Boost Video Card 1GB
Win7Pro 64-bit
Obviously DVD, Case, etc.

All of this comes to around 800 which is where I want to be. How does it look? I've gone back and forth on the video card but the 560ti is on sale right now for holidays and that swayed me. But, I'm open to change.

Thanks!
