Budget Gaming PC Help!!!!

[Aprox]

Hello there Tom's Hardware people! I am looking to build a great gaming PC on a budget. With this build I am looking for parts that can be upgradable in the future as in new processor, USB ports, GPU, etc. All info is listed below.

Budget: $750
Games wanting to play: Source Games, DayZ Standalone (or mod until SA gets optimized better), and other popular titles on medium to high settings resolution 1600x900 until I get a new monitor. (Would love to see specs to play on these settings with 1920x1080)

If you could leave me some feedback on what PC could do this for this price, I would love that! I have some ideas but not sure how well they would work. You can look at those here:

Any other options would be greatly appreciated, thank you!

get i5 3470 with gtx 760 and 1X8gb ram and in the future you can get another 1X8gb ram. this setup it works wonders.

Changed FX 8350 with FX 8320 + CPU cooler. GTX 760 with r9 270x and used G. skill sniper series for gaming.

IMO you should avoid the other rigs you posted because of the motherboard. It'd be also good if you can add an extra 20-30$ to get a more powerful PSU.
