Specs: Windows XP
From a computer performance perspective, is there a difference between the 5700 and the 6600 cpu? If so, what performance difference should I expect??

They're both based on the same Wolfdale core so they're basically the same CPU. The only difference is the default clock settings. If you have no intentions to ever overclock, the E6600 is the better choice due to it's higher default FSB of 1066MHz (vs 800MHz). However, if you DO intend to overclock, the E5700 is the better choice because it has a higher default multipler of 15x (vs 11.5x). The added multipler range between 11.5x & 15x will provide several other FSB x multiplier combinations that aren't possible with the E6600.

Thanks for responding. Pls pardon my ignorance re overclocking, but how or why whould I want to overclock and what would I doing that would or could make that happen?

Overclocking means to run the CPU at a clock speed that's faster than the default.

For instance, the stock speed of the E5700 is 3.0GHz with clock settings of 15 x 200MHz (800MHz FSB). But if you have a motherboard that supports 1066MHz FSB, you could change the CPU clock settings to 13.5 x 266MHz & run it at 3.60GHz. If your board uspports 1333MHz FSB, you could clock the CPU at 10.5 x 333MHz & run it at 3.50GHz. Generally speaking, the faster the FSB, the better the entire system will perform.

There are other settings that need to be adjusted as well - RAM, PCI, PCI-Express, voltages, etc. - but once you get the hang of it, there's nothing to it. You just have to stay within what's reasonable for the hardware you're working with.

The basis for my question is that I am trying to decide on which Acer computer I should get. I am looking at the Acer AX3910-U3012 w/ the e5700 processor and the Acer AX3910-3032 w/ the e6600 processor. They are otherwise exactly identical, 4GB and 640 GB with all other specs also identical. The price difference is $60, with the 6000 being higher, and I am trying to determine if the cpu difference is worth it from an everyday system performance and usage perspective. Would I notice the difference? Thanks again.

Generally speaking, the faster the FSB, the faster the system. The E6600 is the better of the two CPUs because of the faster 1066MHz FSB, but these CPUs are just Pentiums, not Core 2 Duos. Regardless, you realize that these CPUs are rapidly becoming outdated, right? If you're going to buy a new system, you'd be better off with a Core-i series CPU. The Core-i is similar to AMD CPUs in that the memory controller is built into the CPU, not the motherboard. This type of setup eliminates the FSB & makes for a more efficient & faster system. I have no idea what your plans are, but the majority of store bought computers aren't very good for gaming. If that's what you're after, a video card upgrade will be required at the very least.

Thank you for all of the information you have provided. It has been very helpful. While I will not use the computer for gaming, I will still look into the Core Duo series, probably the i3 series unless I learn that the AMD equivalent is just as good or can get a good deal on a higher performing Intel i series unit. Thanks again.
