AMD FX 8350 8 core 4 Ghz benchmark 9075 I can get for $185
versus any Intel i7 or i5 with comparible benchmarks
Intel i7-3820 4 core 3.6 Ghz benchmark 9005 I can get for $290
again it's cost versus performance, I only have about $1300-$1400 for the system before monitor/s
that needs to include things like optical drive blu-ray writer
/HD which prefer 3 TB +
prefer 16 GB memory
So again I don't see the advantage to Intel, AMD looks better here with a better benchmark rating and quite a bit lower cost...
I'm really sorry, but I'm not so sure on how to respond correctly given that English isn't my first language, but here goes regardless;
If you're building a gaming computer, what are you doing with so much Random Access Memory and eight cores? Games today aren't even capable of using them effectively, barring a select few outliers; you future proofing? Graphic/video design? Four cores and dual 4GB RAM sticks should suffice for almost everything you can play today, unless as I mentioned you're doing more intensive things like making High definition videos and stuffs.
To tell you the truth, I just put an Intel i5-3570K clocked to 4.5 GHz in and it beasts everything. It's a bit expensive, but it's a really solid, very good chip that can handle anything a game can throw at it. It never overheats, it meshes well with a variety of good motherboards and the like. It also has a really good built in graphics package.
I was contemplating going to Haswell, but this is a really good chip regardless.
Right now it's $230, but on black friday and boxing day it should be really cheap.
This is just my personal recommendation based on my own experience with computers, which goes back to the late 90's, so put as much or as little stock in it as you like. Best of luck making your computer :3
