New Rig, P35 chipset or P45?

[bobjoe275]

Awhile ago, someone recommended I get the P35 chipset for my rig:

I saw a related board with the P45 chipset:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128344

And I was wondering what is the difference between the two? Is one better to overclock than the other? And I noticed one uses PCIE 2.0 and I was wondering if that was worth the extra $30.

For the rest of the rig I'm using a q6600 cpu and this memory:
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1000 (PC2 8000)

I was going to use this heatsink:
XIGMATEK HDT-SD964 92mm Rifle CPU Cooler - Retail

And I'm deciding between these two 8800gt:

If anything is out of whack I'm up for suggestions!

if you're looking to go cf on a budget go for the p45. otherwise there is no good reason to choose a p45 over a p35.

I'm going to take a longshot in the dark and guess that p45 boards are 45nm ready without having to take the chance that you might need a 65nm to flash them like some p35 boards still shipping today with old bios.

That would be worth $30 to me

...course op is using 65nm so it doesn't matter >.>

The P45-DS3R just came out, so it has a nice price premium stuck on there. P45 is P35's die shrink replacement. Its 45nm, so theoretically uses less voltage, and therefore runs cooler; and therefore should OC better. However, not enough reviews are out, so wait a few weeks for more reviews. PCI-E2.0 alone isn't worth $30 to me, but if it turns out that the P45 can OC better and run cooler than P35, then those two things alone are worth $30, IMO; especially since the DS3R doesnt have heatpipe cooling for the NB/mosfets.

If you can wait, do so. If you can't wait, the P35-DS3R is a great board. I can push it to 6x530Mhz with my E6750, but it needs an additional fan on the NB or a better HS once you get past 400-425Mhz FSB SDR. Then again, with a Q6600, you'll never reach above 400Mhz unless you lower the multiplier, so the poor NB cooling shouldn't be a concern for you.

Oh, and pick this up:
$7 - XIGMATEK ACK-I7751 LGA775 Bolt-Thru-Kit
