I just got the sythe s-flex fans, they are great and easy to install. BFG is good, EVGA is good. Can't go wrong with either. BFG has lifetime warranty I think. But I have always bought EVGA and they hold value well when I go to resell them. As for mobo manufacterers, I have Asus, and I have EVGA. Both are good. Asus you pay a premium for but they are solid boards. I went with the EVGA because of overclocking options, and the price was better. My last Asus A8N-SLI deluxe did not overclock well so I thought I would try this board. And I am not dissapointed. I hit 3.6GHZ!! I was stable for 8 hours using super pi and prime 95, BUT, my temps were way too high. I just ordered water cooling euipment today so I am excited to get that in and try and push this thing to the max. E6600+water cooling equipment, including blocks for GPU, was less than top of the line Quad Core, BUT, I will see if I can clock as high as those guys are.
