My wife had a stone age-old laptop with Intel HD 3000 integrated graphics that was absolutely useless for gaming so she constantly used my computer for playing titles like Crysis (1,2); Farcry(3.4); Payday 2 and GTA V. I wanted to build a PC that could run these titles at 1080p on high settings.
CPU: At first i was looking at Intel i5 CPUs for this build but found out about this FX-6300 that it is twice of the i5 price, with 6 cores and good for overclocking so i went for AMD.
GPU: I wanted a GPU around 200$, in this price range had to choose between GTX 960 and R9 380. R9 380 has a little better benchmarks so i choosed this card. Overall im satisfied with this GPU. I get decent frame rates (40-60fps) in all games with very high settings.
CASE: Really like the cases Fractal Design makes. Define S is designed for water cooling builds but air coold system can be built in this case with no problems. This case has great built in cable management features for a clean build. Its good looking and silent. What more could you want. x)
I expect this build to run for about 1,5 - 2 years. Will probably upgrade it to GTX 970 after that as i have seen builds with FX-6300 and GTX 970 with good results.
