I just want to know if there is anything wrong with this gaming build.

Solution
For a gaming build you want to spend more on graphics and less on CPU.
You are most likely to be better off with an AMD build, though an Intel i3 build is economically viable.

Something like this wouldn't be a bad template for that budget region-

Hi!

Your build looks great provided it's for general desktop use. You could even drop your PSU to 450W and the RAM to 1333MHz and not notice any difference provided you're not gaming.

If the PC is for gaming, it needs a bit of a rethink. Post back if it is.

There is likely to be quite a lot of movement in that graphics card area in the near future I think, as the R7 265 should mess things up a bit. Right now it's either an overpriced GTX660 or overpriced R9 270 at the $180-200 bracket. If the R7 265 does land at the $150 price, it'll be a really nice buy.
