I am in process of upgrading my system to Core i7. Already decided on i7-920 after taking a quick look at Lynnfield, but I still have doubts about board to get.
I can either get a good Tom's Hardware recommeded budget board ASRock X58 EXTREME or have Intel DX58SO for a similar price. Assuming price is not a factor, which of the two boards have better performance / feature set? Are there any real contenders under $200?
Right now my plan is to slightly OC and put a single moderate GPU (having dual-GPU option open in the future would be a bonus).
I just replaced the mobo in my i7 machine from a DFI LP DK X58-T3eH6 with an ASRock X58 Extreme.
Albeit this is not a direct comparison to your situation but the reason I swapped out the DFI for the ASRock was due to compatibility issues and a buggy BIOS with the DFI plus all the stellar reviews and write-ups about the ASRock X58 Extreme. I also have ASRock mobos in my HTPC and NAS and they have been running stable without any issues, so why not try one in my gaming machine.
To further clarify, I am using a Highpoint RocketRAID 2310 and 4-80GB WD drives in a RAID0 array as my OS drive. The DFI board consistently "forgot" that the 2310 controller card was installed, "forgot" the boot order, and "forgot" memory timings and overclocking settings. Believe me when I say I tried everything from ensuring the latest firmware and driver updates to even replacing the battery. Tech support from DFI was basically useless because I was/am using a 3rd party RAID controller. So, my solution was to swap out the mobo. After plugging on all my devices and components into the ASRock, I could tell after second reboot that the compatibility and BIOS issues I had with the DFI mobo were/are completely gone.
Even though I have only been using the ASRock X59 Extreme for less than 3 days, I can say with some confidence that the reviews on Newegg are legit, that the X58 Extreme is a quality i7 platform at a reasonable price, and the EZ overclocking settings are truly EZ. Another bonus for the ASRock over the DFI was that the ASRock recognizes memory XMP profiles. Nice!
I can recommend the ASRock X58 Extreme and I can especially recommend it over the DFI LP DK X58-T3eH6!!!!!
