This practice consumes considerable time especially if it is implemented in three processors. Thus the final results are estimates placed great emphasis on stability because although higher frequencies can be achieved is useless if not support some charges (not necessarily have to be intense).
CPUZ - Intel i7 870

Not being an Extreme or similar processor does not allow manually increase the multiplier (at least I could) and hence will orient the eye to the system bus increased to almost 160 MHz (fully stable) and that higher levels are different types of errors. Finally we reached a speed of 3.47 Ghz acceptable base where information about the voltage is not perfect.

After analyzing their behavior and passed the 3.4GHz processor has a fairly high capacity of OC to be one of the strong points. Moreover if we apply Turbo Boost can get even more performance but everything has a certain limit.
CPUZ - Intel i7 860

It is somewhat difficult to do some OC tests are not taken especially when some settings, perhaps because the DP55KG not have enough confidence to implement it. In this case we go up to 3.3 GHz base demonstrating that also has an initial capacity actually tolerable.
CPUZ - Intel i5 750

This processor has cost me a lot of work because the system does not accept certain values (directly does not turn on or take anything). Anyway we managed 3.2 GHz base that are attractive in my opinion.

With the arrival of new P55 motherboards we know more about the potential of these processors in future reviews.
Synthetic Tests

Let's see what behaviors get in the synthetic tests starting with the old familiar 3DMark 2006.
3DMark06

With the latest Forceware drivers, the Lightning and NGTX275 Lynnfield processors reach a stunning performance which exceeds the i7 870 tranquilly 17,000! The i5 750 also doing his bit with a more than welcome.

On the one hand and Turbo Boost HT applied to the series i7 800 where the harvest undoubtedly cast impeccable performance although the i7 860 inexplicably does not make a significant difference. Furthermore, we apply the i5 750 OC (next to the Turbo Boost) generating a forceful shot on a par with Intel's most powerful model for socket LGA 1156.

Seeing the performance of the processors in the application, we note the strong increase each bring to apply their technologies where i7 870 shows strength and determination to reap the maximum performance time.
3DMark Vantage

Virtually no global perceived marked differences among themselves by providing competitive scores where GForce GTX 275 Lightning accompanies an acceptable configuration with dual-channel 1600 MHz (XMP).  

If you look closely at the CPU scores identifies the role of each one being the most powerful i7 870 especially if you activate the Turbo Boost function.
CPU RightMark Lite

For some strange reason the Core i5 750 has a lower yield than normal product of some variable which bothers the system while the series i7 800 offers significant fps average.

With technologies enabled we noted a significant increase in fps but far from the Core i7 965 Extreme processor for high-level enthusiasts. The i5 750 has a very credible performance given its specifications, so after analyzing the variables at play are some options in the Bios that mysteriously misplaced were configured without permission (usually happens in engineering platforms, will surely be corrected by future BIOS revision). We finally got a Best Bet that goes up to the 84.89 fps.
PassMark Performance Test 7.0

Here we can see the differences between each processor depending on the pocket and applications to use or not. The composite average is constructed after several performance tests that include encryption, multimedia instruction, physics and so on.

Are there differences in performance as the processor memories? In the series i7 800 is very light to be essential low latency settings (if possible) and high frequency (where the system accepts DP55KG hardly more than 1600 MHz).
Cinebench R10

We have seen that the new architecture shows improvements in certain scenarios where the Cinebench is a good example as it uses a single core, multiple cores and video. In principle we note the excellent products that provide both the i7 870 and 860 leaving the i7 relegated to the i5 750 in a more demure.

Now, with the empowerment and HT Turbo Boost performance noisily shoots ahead, for the i7 870, the value of 31,000 showing the magnificent handling of multi-tasking using the 8 threads simultaneously. But here is a resounding note that the absence of HT on the i5 750 comes despite applying penalty Turbo Boost or OC.
HDTach 

With the Seagate 320GB hard drive no surprises as we reap the P55 chipset provides the usual level with an average reading of 65.8 MB / sec (interesting when you consider that it is all integrated in one package).
