Is it worth the extra 100 bucks to get the C2 duo 6850 or is the 6750 a better buy. I will overclock but don't want to go too far. I do a lot of video work and need something fast.
I have another question on what type of board to get. With all the new ones popping up what seems to be the best right now? I know much is on personal preference but I just want some input. Thanks for your time.

The right choice depends less on model numbers and more on how the machine will be used. For interactive editing and previewing, single-thread responsiveness plus GPU acceleration and fast scratch storage matter most; for long batch renders and encodes a higher core count or better multi-thread scaling will show the biggest wins. rightly flags that some renderers make better use of extra cores — confirm whether the specific encoder/effects in use scale well before paying premium for more cores.

When picking a motherboard for a video workstation, prioritize stability and I/O over gimmicks. Key practical items to check:

  • robust VRM design and good heatsinks (important if overclocking);
  • BIOS/UEFI with fine voltage and multiplier/FSB controls;
  • enough DIMM slots and verified RAM support for large projects;
  • multiple high-speed SATA ports (or native RAID/eSATA) and headers for external capture (FireWire/eSATA) if needed;
  • one full-bandwidth PCIe x16 for the GPU and room for capture or RAID controller cards;
  • well-reviewed long-term stability and active firmware updates.

For overclocking and validation: increase clocks in small steps, stress-test CPU and memory (Prime95 / memtest) and watch temperatures; use a dedicated fast drive (or SSD/RAID) as a scratch disk; and keep frequent backups of project files. Finally, when comparing that extra $100, weigh marginal CPU gains against spending on more RAM, a faster GPU (for apps that use it), or better storage—those often deliver larger real-world improvements for video work. ’s pointer to shopping is useful, but prioritize hands-on reviews that test stability and real editing benchmarks.

I replied to your other post about 64 bit. The benchmarks rate the 6850 better than the 6750 in most of the tests. If those tests are applicable to your uses for the CPU, then you'd take the 6850.

I faced that choice too and took the Quad 6600 - but that was for a specific calculation program that will utilise as many processors as are available. So 4 x 2.4 is better than 2 x 2.6 sort of thing in my case.

For video rendering I'd have thouyght that with the right application (and that may be a challenge) a Quaddie is the best bet.

I can't judge which is the best board, but I did have a choice to make and from my signature you can see that I chose nForce because of its affiliation with nVidia; a sort of "feeling" eith no evidence that the graphics card will blend better with the mobo. Prolly of no consequence. But the mobo is good and I'm trouble free.

There are many known Motherboard brands, such as Asus, Abit, Foxconn, whatever. No best, just have the one that is suitable for your own sets. Here is one site I usually go, you can search some that you need
