Thanks, I went through other benchmark tests as well and understand that i7 2600K would give better bang for the buck. My requirements are very simple, I am not a heavy gamer but use Lightroom, Photoshop and Premier a lot and will optimize only for that. I researched a bit more and have more precise questions now ...
1. As of today, Adobe products won't benefit from 2 Graphics card in SLI mode or even a dual GPU card (single card sli). In that case does it makes sense to go for a Z68 mobo? How would Z68 add any value over P67? Talking more with photogs and video editors I've got suggestion to invest in a single GPU video card and pour more in RAM and an SSD for a scratch disk.
2. What does dual channel and triple channel mean for a DDR3 ram? I plan to get G.Skill Ripjaws 16GB (4x4) - http://www.newegg.com/Product/Product.aspx?Item=N82E16820231473.
Is that perfect for i7 2600K?
3. Any suggestions on the cooling and power supply? Any extra needed other than the stock cooling?
