Which of these computers is best?

I will be using the computer for internet use, some 3d games (Minecraft, Civ V, tf2) and that's pretty much it.

Comp #1:

AMD Quad Core
16 GB RAM
Windows 7 HOME Premium or Windows 8
2 TB (2000 GB)7200-RPM Hard Drive
20X Dual Layer DVD Burner
Integrated Video/PCI-E 16X Slot
Tower Case w/ATX Power Supply
HD Integrated Sound Controller
10/100 High Speed Ethernet
1 Year Parts/5 Years Labour Warranty

Comp #2

INTEL Core i3
Windows 7 Home Premium or Windows 8
1 TB (1000GB) 7200 RPM HDD
8G RAM
20X Dual Layer DVD Burner
Integrated/ PCI-E 16X Video Slot
Tower Case W/ATX Power Supply
Integrated HD Sound
10/100 Ethernet
1 Year Parts/5 Years Labour Warranty

Assuming by your usage and specs you provided for both pc. You are not so into this kind of stuff
and you are gonna use either of them for long time, so let me help you
First both the specs are unbalanced and have unbalanced power for the money, high RAM with mid range CPUs and no graphic card is the waste of power(RAM) and won't handle the future applications and 3d games and won't survive for long, with list you provided
so here is the mix recommendation for you
specs
INTEL Core i3
Windows 8
1 TB (1000GB) 7200 RPM HDD (500GB recommended for non gamers)
4GB DDR3 RAM
20X Dual Layer DVD Burner
Integrated/ PCI-E 16X Video Slot
an 1GB DDR5 AMD graphic card ( for smooth running of graphic related apps, hd movies and also playing 3d games)
450W psu
Integrated HD Sound
10/100 Ethernet
1 Year Parts/5 Years Labour Warranty

it may slightly extend your money budget but you won't gonna have any problem(slow) for long time
or if you just want to go with your specs go for Comp#2.

The first is better

Both have there faults but the second one is just slightly Better spec wise
