You don't want to turn HT off, it will improve performance any time you've got more threads running than cores. It may not be worth paying extra for if you don't frequently use heavily-threaded apps, but there's no reason to give it up if you're getting it.

It's 10% faster with 10% lower power usage. If you have a new enough system that that still isn't compelling for you, then there's no reason to upgrade. The new Radeon HD 6900-series drops tonight at Midnight Eastern/9PM Pacific, so check that out if you have a fast CPU already.

I wouldn't worry too much about board pricing yet. Initial indications were of a $20 premium, but that's also supposed to even out shortly after launch. If you do a Froogle search, you can find plenty of P67 boards <$140 or even lower.

I was thinking about going with an i7-950 but the temptation for more performance for the same buck from SB is tempting. Then again, I've done launch hardware before and gotten burned on reliability and I don't know when SB will be available in Norway or the price point (negating the more bang for the buck).

I'd like to see how well 8 graphics cards (or even 4) work when sharing only 16 PCI-E lanes between them. Bridge chips like the NF200 and Lucid Hydra help, but that only goes so far.

Another thing that Sandy Bridge will be good for is GPU computing, since you can use the onboard video for display rendering and the Tesla card for computing. You have to use special compute-only drivers that doesn't support display output, because Windows won't allow you to perform any compute operations that take longer to complete than the driver timeout window (otherwise it thinks the driver hung and restarts it). The compute-only driver isn't a WDDM (Windows Display Driver Model) driver, so it isn't affected by this. Basically this means you can get away without needing a separate videocard for display in Tesla-equipped systems.

Spite posted:It's not that simple. You'd have to also be aware there are 2 GPUs and data would have to flow well from one to the other. There's a host of annoyances. Similar to why no one has a good solution for dynamically switching between an integrated GPU and a discrete one on the fly based on workload - you have to be able to assume the rest of the system is playing nice, which it most definitely is not.

Honestly I am kinda disappointed in desktop Sandy Bridge. The absence of VT-d and TXT on the K-series isn't really significant, but it feels kind of insulting to cut features out of a premium SKU. The fact that you only get Intel HD Graphics 3000 on the K-series CPUs that are least likely to use it is also odd. It's also bullshit that we can't use Quick Sync without using the on-die graphics, I don't see what keeps them from running the silicon even if it's not driving a display. Given the Quick Sync limitation, the feature division between chipsets (P67 gets dual graphics and overclocking, H67 gets Intel HD Graphics and Quick Sync) is even more frustrating. On the plus side, Sandy Bridge appears to have more than delivered for the mobile sector. Sandy Bridge laptops are insanely fast and have great battery life, and Intel HD Graphics 3000 performs competitively with the Geforce GT 325M, which is pretty drat good for integrated graphics. Paired with a Geforce GTX 560M you'd have a pretty drat efficient mobile gaming system. Alereon fucked around with this message at 18:20 on Jan 3, 2011 |

Even if you do torrent, you're almost certainly not going to care about your NIC chipset. GigE has been common for long enough that even your standard Realtek or Marvell chipset has no problems making it work well.

Not directly Sandy Bridge-related, but of interest to those of you building new systems: Oversupply sends DRAM prices to one-year low. Bulk DDR3 prices, which were predicted to drop below $10/GB by the end of 2010, have now reached only $6.72 per gigabyte. Prices are expected to recover a bit with rising demand in Q2, but before then we'll probably see prices below the record low of $6.48/GB set back in March 2009. Granted these are wholesale prices for the DRAM chips only, and current Newegg retail is about $10.75/GB for DDR3-1333 in 4GB DIMMs, but we can expect the retail price to continue to decline, trailing the wholesale DRAM prices until they start to recover. Those of you in the market for RAM in the next few months might want to consider getting more than you need as a hedge against higher upgrade prices later on. I went to 8GB of RAM when DDR2 bottomed out and it was a good choice. I'd definitely get at least 8GB with any new Sandy Bridge system.

There's still the issue that using 4 DIMMs may mean you need to back off on timings or clock speeds for stability due to the additional load and reduced signal quality, and that you can't upgrade your RAM in the future without replacing sticks. I'd say 2x4GB is the best option right now unless you have a compelling reason to get 4 DIMMs.

Gigabyte's LGA-1156 boards were pretty terrible, they had memory compatibility issues and huge problems supplying stable power to the CPU. The sheer volume of threads in the Haus of Tech Support for unstable i5 systems with Gigabyte boards was insane. It would be cool if they made better LGA-1155 boards, but I'm not holding my breath. Edit: Honestly, I would never buy anything other than Asus, but that's me. Their prices are pretty competitive in most cases, and so the small savings aren't really worth taking a risk for me.

I wouldn't worry about it. Up to 1.40v is generally considered safe for the 45nm CPUs when well-cooled, but my Core 2 Quad Q9550 also hits a wall past 3.4Ghz. 3.4Ghz at 1.30v is fine, but 3.6Ghz requires 1.40v and an excessive amount of tweaking, so I decided it wasn't worth it to try to eek out the last couple hundred Mhz. Every CPU has a point where power usage starts going up near exponentially, it's generally not worth pushing the CPU past that sweet spot.
