New computer specs help?

Not sure what section to put this in, but anyway feel free to move it to the right one.

I'm looking at getting a new gaming PC, currently the one I'm using is 5 years old, and getting out dated, so I've decided to upgrade to a better, more modern gaming PC. Currently I'm looking at 2 computers, and would like some feed back as to which computer would be a better gaming PC.

The first ones specs are:

[size=9]

[size=9]Processor
AMD FX-4170 4-CORE BLACK EDITION CPU 4.2 GHz, ,Total L2 Cache


Motherboard
AMD 970 Chipset Motherboard AMD970 + SB950, AM3+, 4x DDR3, 7.1 CH, GbLAN, SATA3, USB3.0, ATX Form Factor


Memory
8GB(2x4GB) Lastest 1333MHz DDR3 Premium Memory



Graphic Display
ATI HD 7750 1GB DDR5 Graphic Card


Audio Sound
Built
in Realtek ALC889 codec High Definition Audio 2/4/5.1/7.1-channel
Support for Dolby Home Theater Support for S/PDIF In/Out Support for CD
In


Hard Disk Drive
1000GB (1TB) Lastest SATA2 7200RMP HDD


Multi Card Reader
Internal Multi Format Card Reader


Optical Drive
22X Dual Layer DVD Rewriter - Supports Dual Layer (8.5GB) - Bundled With Nero Es [/size][/size]

the second one is a Dell Inspiron 660 and these are its specs:

Processor: 2nd gen Intel Core i3-2120 (3.30GHz, 1333, 3MB, 2C)
OS: Windows 7 home premium SP1 64 bit
Memory: 4GB DDR3 SDRAM at 1600MHz
Video Card: NVIDIA GeForce 620 1G DDR3 (M117N)
Optical Drive: HH SATA tray load DVD+/-RW

I'm not really sure which one is better? are there any computer savy
people out there who can tell me which one is better? Most things are
the same (like memory, hard drive) but its mainly the graphics card I'll
need to be good, I like to play games such as Skyrim, sims 3, diablo 3,
dayz, etc. Most need pretty good graphic cards to run with nice
graphics.

anyway thanks for any help!
P.S sorry if this is in the wrong section...

Hello,

Definitely the first one.
Why not build your own PC?

Thanks for the help

I would, but I honestly don't know what to get, and which is better etc.

//EDIT

Okay, I noticed that I could upgrade the graphics card and these are my other options, which on out of these would be good?:

upgrade to Nvidia GTX560 PCI-E 2.0 1GB GDDR5 256-bit
upgrade to Nvidia GTX670 PCI-E 2G GDDR5 256-bit
upgrade to Nvidia GTX680 2GB GDDR5 256-bit
upgrade to ATI Radeon HD 7770 1G DDR5 PCIe

upgrade to ATI Radeon HD 7870 2G DDR5 PCIe

Hello,

Those are all great and awesome graphic cards, but since I prefer NVIDIA... still, those are all good graphic cards, from what I know.
The 6xx NVIDIA line are currently the newer GPU's.
