Which computer is better for the price?

Well i'm looking to get a new gaming pc soon and im down to 2 choices.

First one is a Cyberpower PC for $1,120

Specs-

CPU- AMD FX-9370 4.40 GHz (4.7 GHz Turbo) Eight-Core AM3+ CPU 8MB L2 Cache & Turbo Core Technology

GPU-AMD Radeon R9 280X 3GB GDDR5 PCIe 3.0 x16 Video Card (HIS IceQ X2 Edition w/ Double Fans)

Memory- 8GB

HDD- 2TB

The second one is a more expensive Alienware for $1,300

CPU-4th Generation Intel® Core™ i7-4790 Processor (8MB Cache, up to 4.0GHz)

GPU-NVIDIA® GeForce® GTX 760 Ti with 2GB GDDR5

Memory- 16GB

HDD- 1TB

I'm not too good with computers so which one is better for the price? Is it worth it to pay more for the Alienware? And if both computers are bad, can I get a link to a better one?

Thanks.
