The R7 265 should be able to do mostly high settings with fallout 4. You should lock your frames at 60fps or 30fps anyway to avoid tearing. It's only placebo. As long as your doing over 30 fps your game will run as smooth as 100fps synced.

If you can get both the cpu and mobo for a reasonable price (secondhand I presume?) you should get it/steal it :-P

of course i5!

whoa dude, its not that obvious…GD says that FX 8350 is 3% better…now lets see…what do you want from ur cpu:
Good single core performance (with not good multitasking)
vs
very good multitasking (w/ average good single core perf.)?

3% doesnt amount to a whole lot and thats just based off hardware comparison on the page its not real world

very few if any even if they did most games arent cpu bound enough to drag down good i5 cpus yet unless its poorly optimized then theres nothing you can do really (im looking at you ubisoft)

I believe planetside 2 uses eight cores but i5s still work wonders on it

yup its great

There is no way the 980 will be bottlenecked by a 3570k

You might want to go with a stronger processor with that graphics card. The RAM would be fine. :)
Sorry for the late response.

It would be fine for any graphics card out there if it is gaming you're doing, it is a really powerful gaming cpu and you can overclock it for a further performance boost.

You will be fine, if you want to match this one with GeForce GTX 980.

This CPU is really good. :)

i have a similar cpu to this and a 970 with 16gb of ram trust me this processor is just fine for games
