I think everybody's excited about SB, and the big big big overclocks.

Here's what I'm interested in:

What is the safe voltage of 1155. What clock speed can be ran at that voltage 24/7.
What is the average clock speed at that voltage. Is it 4.4ghz? 4.5? 4.6?
Clock per clock, what is the exact advantage of SB? 5%? 10%? 2%?

Adding it all up... You might see that a 4.2ghz 920 > 4ghz SB. Or might not. Time will tell...
Yep, we will!

Real world users will help provide this data, so we can know once and for all clock for clock how ALL CPU's perform.

Like in that review earlier, they had the 2600k & 980x @ 4.4, why couldn't they have the 920 @ 4.0 - 4.2, instead of 3.6?

Same for the 1100T, they didn't overclock it either.

I'm having a hard time deciding on my processor and motherboard. My two questions are; Does the 2500k work well with it's stock heat sink? (I missed the sale on Noctua CPU heatsinks) and, is there a motherboard that really stands out in the value segment?

Apparently, one site got it to 4.4 on the stock cooler, but I would still recommend an aftermarket air cooler if you want to push beyond that.

MOBO's, what's ur budget?

I wanted to be below $150 on the mobo if possible.

I wonder why 1155 boards are limited to running in 8x / 8x mode however. I wonder if this will negatively effect multi-gpu set ups.

Because the CPU only has 16 PCIe 2.0 lanes.

how about the UD3P?

We'll see how much the egg sells them for.

I think I need to put this higher up in the OP.

Before digging into Gaming Benchmarks, let's clear up the misconception of whether or not 16x 16x are better than 8x 8x, and this article will clear that up:
http://www.hardocp.com/article/2010/...x16x16_vs_x8x8

What we discovered in this testing were the differences that resolution has on gaming performance in a multi-GPU video card configuration when in x16/x16 compared to x8/x8. In our evaluation last week, we tested at x16/x16 and x16/x8 and found that there were miniscule differences at 2560x1600 and 5760x1200 resolutions. However, in this week’s evaluation testing at x8/x8 and x16/x16, we see that having both video cards at x8 does somewhat impact performance, but only at the higher 5760x1200 Eyefinity/NV Surround resolution.

It seems that at 2560x1600, even with 4X AA, there was absolutely no difference between x16/x16 and x8/x8. This is good news if you game at x8/x8 on a single display configuration at 2560x1600 and below. You simply are not missing anything, and moving up to x16/x8 or x16/x16 will yield no performance improvements or gameplay differences, even on the fastest GTX 480 SLI.

However, if you game in a triple display setup at 5760x1200 or higher, then you might want to aim for more PCIe bandwidth. It seems that you will at least want your primary video card to be running at x16 mode. At x8/x8 we found "benchmarkable" differences in performance. We say "benchmarkable" because these differences were only noticed on a graph.
