Thanks for replying, I have decided to upgrade my cpu to a S suffix one. Can you please recommend a good I5 or i7 s series processor that would go with my setup plz?
You may want to reconsider going with a non-s processor as apparently they run nice and cool (so probably are not using peak power):

You do sacrifice some serious performance gains by going with the s version:

I own the 4770s and it only boosts 100Mhz slower than the 4790s at 3.9Ghz on a single core, but using all cores and threads it only boosts to 3.5Ghz. I would assume the 4790S would be 3.6Ghz all cores. So no, that difference is not as small as you make it seem. The 4770s performs about as fast as a 3770 or my 2600k oc'ed to 4.5Ghz. which is around 15% or 10-13fps slower than a 4770k.The I7-4790S performs almost on par with the I7-4790... you really don't sacrifice some "serious" performance by going this route. They have the same turbo frequency, the S variant having a lower base clock. You'll run on average 100-200 MHz lower on the 4790S which really isn't that big of a deal considering they're basically the same chip, one of them having slightly reduced(4790S) clocks to lower it's TDP.

Those are synthetic benchmarks, not real world situations or game benchmarks. It doesn't really matter though anyway as even an i7 S model is an upgrade over an i3 and an i7 S or T model would be a better match for OPs system with such a low power PSU. The biggest issue may be that the i7 S with the RX 560, could cause total system power draw to exceed what the 290W PSU can handle right now with the i3. The OP will need to buy a 450-550W PSU and an adapter for the motherboard 8pin system power or they're probably going to be limited to at most an i5-4570/4590.
