Phenom II x6 1090T=Amazing!!

Nice, and since you bought the black edition get yourself a new cooler and overclock that baby to 4ghz. Gotta get the full potential!

So I'm guessing this isn't going in your HT?

Yah the stock fan is no good for OC'ing. Most people say keep it under 55c, amd says 62c is the max you should run it at. Amd chips are less resilient to heat. Your temps sound about normal. I would get a better cooler even if you don't oc just to keep it a little less toasty.

Also there is an issue with the temp monitor being like 10c off from the true temp. I would try HWmonitor to be sure you are seeing the right temp. I think its the core temp you wan to be looking at, whichever is the highest.

The hyper 212+ is a good affordable cooler for moderate oc'ing. Maybe 3.6-3.8ghz.

I'd say if you want to do 4ghz your going to want to get something in the $65-85 range.

THermaltake Frio, Corsair H50, Prolimatech Megahalems are a few.

I'll just leave this here

The ref shows mixed results.

IMO hotrodbob has a better sense of what counts, and price.

But then I'm an AMD cpu fan.

Ok as long as you are getting the right number. Good to go.

Mixed results? The 2500k beats the 1090T in almost all of those benchmarks. I think only 3 of those benchmarks the 1090T is better. Higher is not always better in the graphs, some are "Lower is Better." The 2nd pass x264 benchmarks shows the 1090T surpassing the 2500k by 1fps... not very much. I rather pay an extra $25 for the 2500k. Basically the same encoding speed (1fps) and overall better performance with the 2500k.

The 2500k is actually a normal quad core so only 4 threads. Not 8 like the i7. It just has a far superior architecture to the 1090t. The other great thing about it is sandy bridge can overclock like no other. Pretty much any chip can do 4.5ghz + easy.

But either way you got yourself a great chip. And I agree you definitely have to factor in the motherboard cost as you can score a pretty decent AMD board for around $100.

True, Intel motherboards are more expensive than AMD, especially for relative new Sandy Bridge.

However, 6-core AMD consumes way more power than Sandy bridge. If you look at Anandtech CPU bench link above and check power consumption, 1090T system consumes 68 Watt more than i5 2500K during x264 encode.

You can calculate impact on electrical bill, but in short term it means cheaper cooler with the same noise/temperature stats for Intel. For example, you don't need $65+ cooler to overclock to 4GHz as advised here. $40 Scythe Mugen 2 will do just fine for Sandy Bridge. Simpler case cooling too.

Another thing, in long term Intel QuickSync looks promising for video encode. But, currently there is no chipset that allow to use this and overclock at the same time, Z68 will do it in May. No free software using it so far but this will change.

I'm sure it will be fine. Did you at least get the cooler with the copper heat pipes? Hyper 212 goes on sale a lot for around 20 bucks, great deal but you would have to take out your mobo to install.

I don't recommend overclocking much on that board as it only has 4+1 power phases. (I know I originally encouraged it.)

There has been issues with AMD six cores being overclocked in 4+1 boards.
Your chip should be very easy to OC. It is a blacj edition so it has an unlocked multiplier. So you just raise the multi a little bit, and give it a little voltage. Your board will probably have some auto oc features but those normally suck. They almost always send too much voltage to the chip to over compensate to be sure it is stable.

But like you said you got plenty of cpu power there already. When you get the upgrade bug again, if you don't already have one get an SSD. You will feel it more then a new cpu.

With your chip its real easy. You can start by raising the mutlti to whatever gives you say. 3.6ghz. Run prime95. If it fails or blue screens bump the voltage a little.

Heres some info

This is my favorite site heres the section for your cpu, tons of info there.

SSD will help your os and overall pc experience be much faster. You can get a big enough one for ~$100. For all the money people dump into pc's this is a small amount.

Not really. SSDs are for snappy user experience, faster program startup, etc.

If you have 5400 rpm drive what would probably help is a second hard drive. One for input files another one for output. This way HDD doesn't have to do extra seeks. This is true if HDD is your bottleneck, and not CPU (which is probably true with 6-core).
And if you mostly encode from DVD drive disregard this.

6450 rpm fan must be loud. It probably will work but Hyper 212+ advised here is a very good cooler, it will just make things quieter. Being on sale for $23 at J&R right now it is a good buy (shipping fees are high, but it's still OK, or you may find better deal somewhere else later).

Try raising CPU speed without increasing voltage first. I don't have any experience with recent AMD CPUs but my Core 2s can overclock from 2.83 to 3.4GHz and from 3.0 to 3.6 without any voltage change.

It's a general rule is that increasing voltage is needed to overcome stability problems. You run Prime 95 for couple of hours, if all things work there is no need for voltage increase. If there are sudden crashes then need to ether increase voltage or reduce CPU speed.
Everything else is in the guides.

1. Use a large heatsink/fan(120mm) as that will run at rpm of 800 to max of 2000 rpm. In my home machines I use Cooler Master; both C.M. Hyper 212+ (requires case that is at least 8.0 inch thick, as fan sits tall), or C.M. GeminII S which sits flat so can be used with a less thick case. Both usually require mobo to be removed in order to install the heatsink/fan. Of the two I like Hyper 212+ best. Check both newegg and amazon on price before buying anything.

These aftermarket coolers offer both better cooling and especially lower noise, over the stock sink/fan.

2. I see that the AMD 1090T is a 6 core black edition. Go easy at overclocking as the 6 core AMD Phenom II is specked at 125 watt power draw, which is max for many mid priced AMD mobo.

3. With regard to lower energy draw of recent Intel cpu's. my one thought is that the price premium that one pays for Intel cpu's will buy a *lot* of electricity.

OTOH, I see that Intel seems to be winning the battle cox 3 months ago newegg showed roughly an equal number of AMD and Intel desktop cpu's, whereas just now the count is AMD 28 vs Intel 52.

4. FWIW, I use AMD Phenom II 3 and 4 core cpu (all back edition), and am happy with them.
