Mobo Questions

Ok, it's been 5 years since I last built and overclocked a system and a lot has changed in the interim.

I've decided to build a system based using the Intel Q6600 chip and the ATI HD 4850 video cards in crossfire mode and I hope to overclock both the CPU and GPU.

I've been doing a lot of reading in the forums about the various experiences of people and how successful they were in overclocking the CPU.

I have 2 questions:

1) I'm obviously going to buy a mobo that supports the CPU, I've noticed that on some of the 'marketing' on the retail box of the board, it states that it supports SLI, which I know means the board supports running 2 Nvidia based graphics card. That being the case, does that mean the board won't support running ATI graphic cards in crossfire mode? For example, here is a link the EVGA 123-YW-E175-A1 LGA 775 NVIDIA nForce 750i FTW SLI ATX Intel Motherboard - Retail http://www.newegg.com/Product/Product.aspx?Item=N82E16813188026 The product has 2 PCI slots and I assume it supports running Nvidia cards in SLI mode. Would this board support running 2 ATI cards in crossfire mode? Or would I need to buy a card like the ASUS P5Q-E LGA 775 Intel P45 ATX Intel Motherboard - Retail http://www.newegg.com/Product/Product.aspx?Item=N82E16813131296 mobo in order to run my HD 4850 in crossfire mode?

2) Can anyone recommend a mobo that meets the following criteria?
a) between $100-200 dollars
b) supports the Q6600
c) overclocking friendly (lots of tweaking options in the bios for FSB, voltage, etc.)
d) supports ATI in crossfire mode
e) supports up to 8GB of RAM
f) is version 2.0 PCI and has at least 2 PCI-E (for crossfire mode of course)

Thanks all.

You are correct! NVidia chipsets will not allow Cross fire to run on them, and vice versa with intel boards.

There is a server board that will use both, and I think a skulltrail board as well!

You are better off with the P5q series anyways, lots of tweaks like you want.

BUT, here is the SECRET!!

BUY an OEM q6600!

I CAN'T stress that enough!

With a OEM chip, you have your 1 in 15,000 shot at a low VID! And trust me, if you wanna over clock, you want a LOW VID!

Very smart of Intel, the prices are amazing for the OC abilities they have with the new chipsets.

Poor NVidia. Intel restricts them to Spec when using their processors, because that's all their license is for, to copy the tech, not implement it.

So of course Intel boards with Intel chipsets AND intel processors work nice together. Think they have to tell NVidia the rest of the tricks to getting it all to be nice? Hell no!

Think NVidia likes that? hell no! Wonder why they don't want SLI on Intel boards! Because who would buy a F-ing piece of trash NVidia board then? I wouldn't! SLI on the Formula series = OC heaven!

If you want to Crossfire I would go with the P5E Deluxe. Its $220 and has 2 16x PCI-e slots the P45 chipset runs 8X/8X in crossfire. I knoy its only like a 10% gain in the 16X/16X but at higher resolution that can make a big difference.

i second that it's $210 actually: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131297

great ratings among users. i'd say this would be your first and safe choice. ASUS still has one of the best BIOS support out there so that would be icing for you.

Thanks for the suggestions.....on the P5Q deluxe, one of the reviewers said the p45 chip on the board didn't run crossfire very efficiently at high resolution since 8x wasn't enough. They suggested getting the x48 chipset. Any thoughts on that?

I just saw the P5E deluxe uses the x48 chipset and is $219. Only 3 reviews so far on this board though.

I'm gonna use the system for primarily 2 main purposes, 1) high def video editing and 2) gaming.
