Need help picking a Mid-Range Gaming PC

[RevBlueJeans]

Hey guys, first of all I apologize if this is in the wrong forum section. I didn't see an area for PCs but instead just the individual components.

I would like to pick a mid-range gaming pc, I am on a budget of no more than 650$. I have found two system that I "think" are mid-range and I wanted to see if anyone could give me some advice on which one of them would be the better of the two options.

iBUYPOWER Gamer Extreme NE625FX
-AMD FX-Series FX-6100(3.3GHz)
-8GB DDR3
-AMD Radeon HD 7770 1GB

iBUYPOWER Gamer Extreme NE721i
-Intel Core i5 3350P(3.10GHz)
-8GB DDR3
-NVIDIA GeForce GTX 650 1GB

The games I would like to play are The Witcher 2, Skyrim, Diablo 3 and Dark Souls: PTDE. Which one of these systems would be the better of the two for playing these games.

Thanks in advance!

I just realized that I put this thread in the wrong section and I've also decided to just build a gaming pc instead. If a mod could please delete this thread it would be greatly appreciated!
