80 Plus (trademarked 80 PLUS) is a voluntary certification program intended to promote efficient energy use in computer power supply units (PSUs). Launched in 2004 by Ecos Consulting, it certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. That is, such PSUs will waste 20% or less electric energy as heat at the specified load levels, thus reducing electricity use and bills compared to less efficient PSUs. Sometimes, rebates are given for manufacturers who use 80 Plus-certified PSUs.

For instance, a 600-watt power supply with 60% efficiency running at full load would draw...

Yes, it is what usually happens when i tend to play Battlefield 4 or Cod Ghosts My System reacts as abnormal it hangs and sometimes it just gets off & i am thrown to some sort of message Box where "Close application or find the solution through internet" pops up.

Your CPU is somewhat weak for modern day games, and the PSU is also not a trusted unit, and not even 80+ certified.

You can get a HD 7790 almost in same price range as HD 7770. But its your call.

If you are on 32bits OS then 4GB RAM is fine, but if you are on 64bits OS then I would suggest you 8GB of RAM for better game play.

For instance, a 600-watt power supply with 60% efficiency running at full load would draw 1000 W from the mains and would therefore waste 400 W as heat. On the other hand a 600-watt power supply with 80% efficiency running at full load would draw 750 W from the mains and would therefore waste only 150 W as heat.
