How To Evaluate Clock Speed, Cache, and Bus
rocessor speeds are important indicators of speed, but only when compared with CPUs in the same series. Two other specs—Level 2 (L2) cache and front-side bus (FSB)—also play an important role in overall performance. As for clock speed, a 2.66GHz Core 2 Duo E6700 runs faster than a 2.4GHz E6600, for instance. But it's important to note that clock-speed comparisons aren't valid when looking at different architectures. The lower-end 1.86GHz Core 2 Duo E6300 outperforms the older 3.6GHz Pentium D 960, for instance, and the 2.66GHz Core 2 Duo E6700 bests the 3GHz Athlon X2 6000+ in most benchmark tests. A processor's L2 cache memory speeds up operations by making recently accessed data immediately available to the processor. A larger L2 cache serves up a bigger performance boost on Intel processors than on Athlon 64 X2 chips, due to the methods each chip uses to access memory (more on that later). The FSB determines how fast the processor communicates with the memory controller. It's a factor only on Intel processors, which have varying FSB speeds. A faster FSB can speed RAM-intensive operations. Intel's newest chips use a 1,333MHz FSB. The original Core 2 Duo E6000 series chips employ a 1,066MHz bus, while the E4000 series uses an 800MHz bus. On AMD processors, the memory controller is located on the chip, giving the processor faster access to it; the actual memory transfer takes place over the HyperTransport bus link between the processor and the memory, so FSB ratings aren't an issue with Athlon processors. The effect that cache and FSB have on performance depends on the program you're running. A 1.86GHz Core 2 Duo E6320 can best the 2GHz Core 2 Duo E4400 in some tests, due to its larger cache and faster FSB. Realistically, though, in most operations these differences are small.
do you need 64bit cpu?
Why You (Don't) Need 64-Bit
While most of today's software is designed for 32-bit processors, all of today's midrange and high-end processors from Intel and AMD support 64-bit instructions. Though the technologies have different names—Intel 64 and AMD64—they're compatible in all practical ways.
To take advantage of 64-bit software, you need to run an operating system that specifically supports the technology, such as the 64-bit version of Windows Vista. You'll also want to look for applications specifically written for 64-bit processors. A few 64-bit apps are available today, but even when running 32-bit software, multitaskers can still benefit from 64-bit processors' ability to address more than 4GB of RAM.

Budget CPUs: Less Than $100
Both AMD and Intel offer entry-level processors that cost less than $100, yet deliver dual-core functionality and performance adequate for modest use.
Intel has introduced the Pentium Dual-Core E2100 series, which starts at around $90. Despite the Pentium name, these new chips are actually based on the same design as the Core 2 Duo. These new CPUs run on an 800MHz bus at 1.6GHz (E2140) and 1.8GHz (E2160) speeds, and fit into an LGA775 socket.
The Pentium Dual-Core series is almost identical to the Core 2 Duo E4000 series, except the chips contain only 1MB of shared L2 cache. For some digital media applications and games, the smaller cache will yield noticeably slower performance. But even the slower processor is powerful enough to run most recent games at moderate resolutions, making the Pentium Dual-Core an excellent choice for budget systems, at about half the cost of midrange Core 2 Duo processors.
With street prices under $30 for entry-level Semprons, they're worth considering if every penny matters.
Given that their prices start at under $60, AMD's entry-level Athlon X2 CPUs can be a great deal. If you're really strapped for cash, consider the AMD Sempron 64, which supports AMD64 instructions like the Athlon X2 does, but has only a single core. With street prices under $30 for entry-level Semprons, they're worth considering if every penny matters. Most users, however, would probably benefit from investing a few more bucks in an Athlon X2.
AMD is also touting specialized energy-efficient Athlon X2 chips, such as the new Athlon X2 BE-2350 ($91) and the BE-2300 ($86) that fall into the budget category. The 2.1GHz BE-2350 is comparable in performance to an Athlon X2 4400+, but it's rated at 45 watts of power usage, compared to 89 watts for the standard Athlon X2 4400+. The lower wattage won't save you much on your home electricity bill, but it will result in a cooler-running chip, which helps reduce heat and fan noise in home theater PCs.

computer desk
Many people will look at computer desks and see just that, however what you may not realize is how important to our lives they have become. The average person actually spends about three hours a day sitting in an office chair, whether surfing the web, doing paperwork or homework, there are even some people who spend more time at there computer chairs then they do sleeping in there own bed. This means having a work station in your office that properly suits your needs is crucial to being productive in today's business world, whether it’s a chair with proper ergonomics or a comfortable place to do business, we should not take our working environment for granted.
