-The 4850 x2 feedback on newegg is quite limited. From what I see, the 4870 X2 wouldn't be worth the extra $160, but I could be convinced otherwise.
-I choose the asus P5Q pro mobo, but the gigabyte EP45-UD3P is better in some respects. I hear the P5Q pro has an easier to use BIOS, but the UD3P is easier to OC and has fewer overheating issues. However, I am inexperienced with using any BIOS, and OCing isn't something that's vital. Is the P5Q pro the best choice for my needs?
I don't trust tower coolers on CPUs. Make sure you find benchmarks somewhere for that Xigmatech. I have a Zalman's CNPS9700, and it keeps my E8500 freaking frigid.
The anti-static wrap really isn't needed. Just make sure you touch something metal every once in a while, and you're fine. You can plug that PSU in and keep it off. The PSU is now grounded, so you can just touch that every once in a while. I work in a chemistry lab, so I just knick latex gloves because it looks cool building computers with fancy gloves on. It's not really needed though.
