What are some best NON-Alien FPS games??

[Harshilvijay]

So I'm getting my first gpu after few days.
Its a HD6670 DDR3,two years old with one year warranty for 2500INR or 40$.
I like COD series very much and Far cry3 too and haven't played any other FPS games.
So I want the names of some other NON-ALIEN FPS games which would work good on my PC.
My PC specs are
3.3ghz Intel Dual core e5700
4GB DDR3
450w PSU
320GB HDD
Windows 7 Ultimate 64bit.
I want to play those games at least on Medium to High settings with 1366*768 resolution.
Please answer.
Thanks for reading.

Technically the Doom games don't have aliens, just various Demons and monsters.
Most of the baddies in Half Life2 are human/machine.
Again, not aliens but various ghosts/creatures/soldiers: The entire Wolfenstein series, but don't go for Wolfenstein The New Order, it'll overwhelm the HD6670.
If you can find them, the Medal of Honour series.
Again, some are hard to find but the Splinter Cell series but be aware the later games will run slowly on the HD6670, and the same applies to the Metal Gear Solid series.

If you can find it, SWAT 4 is also a good one. It's an FPS, but more along the lines of "shoot from cover or behind your target, because if you charge in you're going to die quickly".
