Point 3:
My suggestion costs $60 less, performs the same/better than yours, consumes less power, it is cooler and quieter. The only reasonable explanation, of why you continue, is that you are a die-hard fanboy, and we hate fanboys here. Most of them are over at Anandtech fighting the AMD/Intel, AMD/nVidia war till infinity and beyond.
Off-topic Point 4:
Arrogance, refusal of arguments right in front of your eyes and the lack of the ability to comprehend what the other communicates, while continuously misleading people does qualify as a sufficient argument to attack another on a basis, questioning their knowledge and/or experience and/or skills.
While neither of us can start throwing diplomas and certificates, the fact that you are TH member for just a month and you do not particularly shine with good knowledge combined with the above mentioned criteria, lead your own arguments to be invalidated.
Off topic Point 5
This forum is not about personal ego, or trying to obtain "guru" whatever status or to beat up personal issues. This forum is about helping people and all of the TH trusty forumers will bash any misinformation or misleading whatsoever. I got bashed as well few times, now it is your turn.
