It still only has two cores and a tiny amount of cache and is missing some of Intels more advanced features.
People have been drinking the kool-aid with this thing. Yes it is a good CPU, yes it can overclock, and yes it has good single core performance. However, it is out paced quite a bit by the FX-6300 in most tasks and CPU heavy games with good multicore support. Based on the games you listed it would really only beat the FX in DayZ. All the other games should run better on the FX. Which of course can also OC like a beast..
You won't do much OCing with that cooler you have anyway...
I suppose it would allow you to go to an i5 in the future but ehhhhh...
I don't wanna get into this debate again though. It gets ugly....
The SSD thing is meh too. I don't know too much about those drives but I don't like Sandforce. That and really you wanna get a 1TB drive first. After formatting, Windows and a few programs you'll be down from 120GB to maybe 80 or less. Games can be up to 50GB these days. A few games pictures, music, videos and files and you'll be full. Get a WD Caviar Blue now.
The rest of your build looks good except for that PSU. It is garbage. It has only a 3 star review on NewEgg. Jonny Guru said it had build quality issues and we have had people on the forums have problems with it. Plus it has many weak 12V rails. While that should be okay with the 7870 any card that draws more power may overload one of the rails and cause instability. I would find something else. You could do better for the money.
Yup and thats linus and not you having to oc it to get your performance out of it. Its still only a dual core missing several features. Your only stepping backwards just for the novelty of oc'ing a intel dual core. So, a poor choice. Which one of those i3's held its own with a the 6300. That would be a much better choice. If your thinking of the future i would go ahead and save for an i5 or i7. I can put together a rig with more cpu grunt and gpu grunt for that price.:)~
Well, even with a mild overclock, most games that OP is playing should run well(DayZ, CS:GO, etc). Games like BF4 might be a bit harder to run, but otherwise it should be ok. Going with a cheaper Z97 board and an i5 though will be a real performance changer.
