"If you are dead set on an Intel CPU, obviously the question that Im sure is on those peoples minds at the moment is whether you should opt for the Q6600 or the E6850, which are both at similar price points. Personally, I would opt for the quad-core processor every time, but thats because Im quite a heavy multi-tasker and I often find myself short of processing time on a dual-core processor. I like to be able to continue what Im doing when Im running a processor intensive task and, since most applications benefit from no more than two cores, you'll still have plenty of processing power available."
"We are at the stage now where Intel can really seem to do no wrong and the E6750 and the QX6850 continue this trend. There are no real breakthroughs in technology with these processors, essentially "just more of the same but faster", that said this does not stop us from seeing some impressive increases in system performance. The main example of this is in the memory bandwidth of DDR2-1066 which takes a huge leap over the 1066 FSB processor based systems. The benefits of the higher FSB also show real world increases in performance and taking Photoshop as an example we saw our best ever result on the QX6850 CPU. It was also nice to see that given the right cooling the potential is there to overclock both new CPUs considerably and our Vapochill system was able to squeeze more than 1 GHz extra out of each processor.
In summary, the E6750 is a great performing CPU which will provide excellent performance across a multitude of applications for a very reasonable price. However the QX6850 is the fastest desktop processor we have used to date and as a result is a worthy winner of our "best in class" Gold Award."
The Core 2 Duo E6750 is not something special except for the overclocking capabilites. When I decided to overclock it, suprisingly it did go a long way. At stock settings the internal FSB is set at 1333Mhz (cpu FSB 1333 : 4 = 333Mhz and using a multiplier of 8 adds up to 2660Mhz), without any extra cooling I managed to increase the FSB to 1800 which left the cpu running at 3,6Ghz. Now that's pretty amazing for a cpu that's cheaper then the E6600 (which also clocked like crazy). I think that it will overclock it bit more when using a better cooling solution. This makes this cpu a good and affordable choice for those that want to give overclocking a chance without killing your piggybank to get it. Its currently selling for for $ 194,- (unboxed,OEM).
The Core 2 Extreme QX6850 is a upgraded QX6800. Meening it has 4 cores, 8MB cache but the internal FSB is set at 1333Mhz just like the E6750. Do keep in mind that you need a motherboard that is able to handle it, perf. a Intel P38 or X38 or a nForce 680 based motherboard. Overclocking this badboy is realy good fun, seeing it has a unlocked multiplier. This makes it possible to try any possible setting to get the FSB running stable at a high setting. After trying numerous settings I got stuck at 3,7Ghz (runnning the cpu with the multiplier at 10x370). Seeing that the QX6850 is running at 3,0Ghz stock a 700Mhz overclock might not seem much but given the fact that all four cores are overclocked as well makes it brutal badboy. Given the benchmark results and the overclocking capabilities it does make you wonder if it's wurth the money (currently priced at at $ 944,- (unboxed, OEM).
"Having a Front Side Bus (FSB) of 1066MHz is old news as Intel has now officially moved over to a faster 1333MHz FSB that helps improve performance. The Intel Core 2 Extreme QX6850 is now the flagship processor and rightly so as it dished out the pain with ease. The Intel Core 2 Duo E6750 offers some serious bang for your buck and should be popular this fall for the back to school shopping season."

"Generally speaking, the higher front side bus speed that the Core 2 Duo E6750 has results in some slight performance increases over the Core 2 Duo E6700 and its 1066MHz front side bus. That's not a bad thing, but to be fair, we werent expecting much more than that in all honesty.
If we look at performance as a whole, the Core 2 Duo E6750 is faster than any dual-core processor that AMD has in its ranks and thats why AMDs Athlon 64 X2 6000+ pricing is as low as it is. Speaking of which, there were quite a few occasions where the Athlon 64 X2 6000+ was faster than Intels Core 2 Duo E6600, which comes in at the same price point."
"While the E6750 isnt primed to set any land-speed records in its default form, it does indeed get very interesting in an overclocked scenario. In our speed of 3.56GHz it easily surpasses the X6800 extreme edition and at a significant cost savings. Fact is, we could have another Celeron glory-day revival with the new chips. Were very pleased with the results of the E6750 and are looking forward to tinkering with the rest of the family of 1333MHz parts from Intel later this summer."
"If you're running a 1066MHz FSB Core 2 processor, there will probably be little point to upgrading to the 1333MHz FSB version when it is released later this summer, even if you have a motherboard capable of supporting the higher clocks. You should definitely wait to see what Penryn brings to the table."
"On all our tests Core 2 Duo E6750 performance was identical to Core 2 Duo E6700, even though it uses a faster front side bus and we simulated the use of several different types of application.
So what is the advantage of using a Core 2 Duo E6750 instead of a Core 2 Duo E6700? Based on the results from our tests, none."
"Other than the chip's performance and overclockablity, there isn't much more we can report in regard to the Core 2 Duo E6750. Intel will be talking about pricing and availability sometime in the not too distant future. Our performance and overclocking data reveals some interesting information, however. As we've already mentioned the E6750's higher-clocked front side bus frequency resulted in more memory bandwidth which in turn resulted in somewhat higher performance overall versus the similarly clocked E6700. More interesting - at least in our opinion - is the E6750's new core revision and stepping, which resulted in massive overclocking headroom. Overclocking isn't a given of course, but if our sample is any indication of what retail-ready E6750's can do, these chips are going to be quite popular when they are released, as long as pricing is in line with Intel's current offerings."
