Which of these is best? Any suggestions?

[Theres a snake in my boot]

Hello, I've decided to buy an off-the-shelf PC for the first time.
I've got an $850(USD) budget. (Can be risen to $1000 if required.)
I know this is a fairly low budget but, I don't have much time between school and work.

I'm strictly a gamer. No recording, no editing, on the internet a good amount.

LENOVO K450E
Intel 4th Generation Core i5(3.2GHz with Turbo Boost up to 3.4GHz)
8GB(DDR3)
2GB (dedicated)
NVIDIA GT 720
SATA III (7200 rpm)
-
CyberPowerPC GUA1200B
AMD FX-Series(3.5GHz with Turbo CORE up to 4.1GHz)
8GB(DDR3 SDRAM)
2GB (dedicated)
SATA III (7200 rpm)
-
Asus Essentio M51AD-B08
Intel 4th Generation Core i7(3.2GHz with Turbo Boost up to 4.0GHz)
12GB(DDR3)
1GB (dedicated)
NVIDIA GTX 750
SATA (7200 rpm)

I'd prefer blunt answers. If these options suck I'd like to just be told that.(Suck for the budget.)
If there's any other suggestions I'd be grateful.

You asked for blunt... they suck!

They all do the typical headline-grabbing thing of high end CPU with barely a mention of the GPU beyond the amount of RAM. The first build is like fitting out a sports car with a motorbike engine.

Why don't you build your own. I'm sure I won't be the only one to suggest this (in fact I'd surprised if someone hasn't made the suggestion already).

You can do way better than that for the money!

Consider these 3

Personally, I like the last one the most, good balance between good CPU and good GPU. While all 3 of these will be good at gaming and run most games at med to high settings (depending on the game), some games MAY NOT work such as AssGreedUnity. Otherwise games like Call of Duty: Advanced Warfare, Grand Theft Auto V, Shadows of Mordor all have their recommended specs met by any of these 3 computers.

Ultimately if you like to game, but don't have much of a budget and want it to last long... get a cheap laptop and a PS4. The PS4 will probably be playing games for years to come. Just throwing it out there.
