First Ever Gaming PC Build for $750-800

Alright hi, im looking to see if what i have here is worth the price of $785 and also if any of you have better build suggestions, im pretty much completely new at this and this would be my first PC build unless this is a good price. The build below is from cyberpowerpc.com where i picked everything and basically if its not that good of a deal i'll just build the pc myself. I'm looking for a pc to run Elder Scrolls Skyrim, Thief, Watch dogs, also smaller games like Left 4 Dead 1&2 stuff like that. 

I use my tv as a monitor, and the os on this build is windows 8.1, a few things i was concerned about was the power supply, CPU, and Video Card.

Thanks for the help! 

Looks good but if you build it yourself you can choose the PSU - standard psu doesn't tell anything- and whatever other brands you prefer. You can get away with a cheaper build by removing the optical disk drive, cheaper RAM and a normal air cooler (if you're planning on watercooling at least get an fx 8350, later batches don't OC as good).  With the money saved you invest in a decent SSD and more in the graphics card and you'll be a happy gamer.
