C2D; Best OC board recommendations?

I'm looking to build a new Core 2 duo based rig, my main objective being to achieve the best CPU/Memory performance on air cooling from a relatively low end processor.

I'll be looking to run the FSB up on a e6320, e4300, e6300, e6400, or e6420 as far as possible, hopefully in a 1:1 ratio with the memory (which will be a 2gb Ballistix pc8500 kit) and would like to reach an OC of at least 3.4ghz.
(Do the newer e6x20's OC as well as the e6x00's/e4x00's?)

My parts list so far is looking something like:
CPU: e6320
Mem: Ballistix 8500 kit
Cooler: Thermalright Ultra-120 extreme

Now I just need a board to put it on. I've been reading around about the performance of various C2D boards as far as OCing and what kind of FSB speeds they can achieve but would like to get a few more solid recommendations/discussion on what board(s) are currently the best for OCing the Core 2. I could care less about whether or not the board can SLI or not, but would prefer to avoid the 260$ monsters if at all possible.

So far I have been leaning towards the P965 chipset, and more specifically the DS3 3.3 from gigabyte, but I have also been reading a lot of complaints. I heard there was some sort of FSB wall that people have been running up against around 450-470 due to a certain resistor on the board that gigabyte was planning on changing out in later revisions of the board to improve it's OCability, and that it reacts poorly with D9 based memory; Is this fixed in the rev 3.3? Are there any superior OCing alternatives to the DS3 from Asus and others? (Like the P5B, etc)

I have also been looking at the brand new P35 chipset; is it a superior overclocker compared to the 965?

I hear that 680i based boards are the best as far as max FSB achievable but can be somewhat finicky, and that they tend to overheat.

Can any of the current above aboards break the 500mhz barrier on a regular basis?
What reasonable FSB limits can I expect to reach using the mentioned parts? (If anyone has experience with any of the specific parts mentioned)

tl;dr version:
What would you recommend as the consistently best current C2D FSB OCing board?

The Asus P5K deluxe will break 500MHz on air pretty reliably from what I've read.

I currently run it at 426MHz since I don't feel I have adequate cooling for the chipset yet... But I've also run it at 460MHz for a test.

All at stock voltages too!

I have 4x1GB Ballistix PC8500 / E6320 as well - but the Tuniq HSF which is comparable to your Thermalright 120 Extreme. (actually, the thermalright is superior with the right fan!)

Other advantages to P35:
- Penryn / 45nm support
- Greater memory bandwidth
- No vdroop when voltage stabilization is enabled. (for me anyway - ymmv)

You might consider going with the 6420 - an extra 1x multiplier might be nice :) On the other hand, I've heard the 6320's are some of the best OC'ers right now - it's always a gamble!

Once I improve the cooling on my chipset, I will see how far this CPU will go. (the heatpipe cooler is designed to receive airflow from the stock Intel CPU cooler which blow air down onto the CPU and across the heatpipes - with the Tuniq / Thermalright, the air doesn't move much around the heatpipes - even so, my idle temp is in thie high 40's and load is 55c or so @ 426MHz.
 
there are 965 mobos that will regularly break 500fsb e.g. abit AB9 QuadGT, Asus P5B Dl/Commando, DFI 965-S.
P35 looks to improve upon 965s abilities though so if there is little difference in price imo you should get a P35 based mobo.
 
Thanks for the quick response.
I probably will end up going with a 6320 on a P35 then; I've always just been a little cautious when it comes to early adoption.
I'll have to take a more in depth look at the P5K, P35-DS3(R/P), and the IP35-Pro... though it has been a while since the NF7 and I haven't really seen a standout product from Abit since.

Anyone having any funky problems like memory compatibility, boot issues, etc with the new boards?

-Also, you could try some simple ductwork to direct air on those Vreg sinks/NB. I cut up a cardboard box and built a bunch of shrouding to modify the air path on my A7N8X way back when I was focused on tuning this machine to it's peak. Its surprisingly effective and costs nothing. Just keep the objective in mind to reduce the volume of space the air is moving through so that your available air pressure is put to best use on your hottest components. Doesn't look the greatest; though I suppose you could paint it or build it out of plexi.

the aforementioned QuadGT is very highly regarded & as P35 is really an improved 965 so the IP35 Pro looks to be heavily based on the QuadGT design ethos.
