I'm just wondering how that looks. I plan on doing some overclocking (3.8ghz most likely), and I have some questions.
1. How well is the stock cooler for getting those speeds? I assume the chip will be a D0.
2. How well is the motherboard and ram for overclocking?
3. Is that RAM decent for overclocking?
4. The ram has high timings, 9-9-9-24 XMP/JEDEC, are those noticable compared to say 7-7-7-19 ?

other than that, how does that build look? Thanks alot.
