You've picked some of the MOST DEMANDING games and while you can find older or even some modern games that would run great I definitely would not want to play these games.
COD AW might be the only one I'd consider playing. It does okay with a dual-core and may look okay if properly tweaked in graphics (Medium/Low, 2xMSAA, 1600x900) thought that's an educated guess.
*You can find BENCHMARKS to indicate relative performance but the problem is they'd be tested with a better CPU than you have.
**My advice is look for different games or build a new PC. At the very least a better graphics card. Use THIS as a guide and compare to prices.

*I recommend the GTX960 above. While 3GB or more might be better for "future proofing" I think when weighing all the pros and cons it comes out on top. (noise, quality, performance vs price, NVidia vs AMD features such as NVidia Shadowplay, H.265 etc).
I think the EVGA 960 cards can turn the fans off completely (the EVGA 970's can).
SUMMARY:
My BEST advice right now is:
a) get a better card like the EVGA GTX960, and
b) avoid CPU heavy games (google for info on that), and
c) TWEAK games carefully to achieve desired frame rate
For FPS, I recommend for example:
a) VSYNC OFF and 40FPS average (use FRAPS), or
b) Adaptive VSYNC and tweak to maintain 60FPS (for 60Hz monitors) 90% of the time.
I used Adaptive VSYNC for AC Brotherhood. If I enabled VSYNC then i got major stutter when I couldn't output at least 60FPS (synch mis-match to monitor). If I disabled VSYNC I got major screen tear (not bad in all games).
Forcing Adaptive VSYNC on for this game only I had VSYNC working until the game dropped below 60FPS then I got screen tearing. I played for a while then dropped from 8xMSAA to 4xMSAA to further reduce the frequency of screen tear.
GOOD LUCK!
