Computers: Build it yourself and overclocking
CPU: AMD 2400+ Mobile Chip - $70
If you are building your own system, choose this chip over the intel one. You save atleast 30% compared to Intel Pentium. And these particular chip are identical to the regular desktop chip except they run at a lower voltage so you can get a highly succesfull overclock out of these. You can reach 3.0 Ghz speed at 1/4 the price.
Video Card: ATI Radeon 9800 pro - $160
This section has been updated, as the Radeon 9500 non pro is hard to obtain now due to dwindling stock. So Best Bang for the Buck, ATI RAdeon 9800 pro for $160 off ebay.
Optical Mice with scroll wheel and side buttons
Need I say more about this. If you ever struggled with a traditional ball mouse that's dirty you waste so much time just wrestling with it to get where you want to go. Plus with the scroll wheel and side button you save seconds that turns into minutes that turns into hours while Internet Browsing
Mozilla Firefox Browser - FREEhttp://www.mozilla.org/products/firefox/
Browsing will never be the same. Think of it has having a Cello on a cigar. It protects you from damage. With builtin pop up blocking and tabbed browsing it makes browsing the CP forums a breeze. I middle click with my mouse wheel on all the threads I'm interested in. It loads them all quietly in the background in different tabs under the same window. And I will go to each thread when I'm done with it, versus the traditional Click on a thread, then go back, and then figure out where you are, or Right Click and Open New window over and over again.
RAM upgrade
If you ever needed the best bang for your buck in terms of an upgrade to a slower machine, there is no single component that can quickly add as much as a 30% increase in speed then a simple Ram Upgrade. Merely adding a 128 stick of ram to a system with 64 megs of ran for $20 and you will see almost a 50% jump in speed and less harddrive crunching. And of course, law of diminishing returns, add 128 to 128, and you get 25-30%, add 256 to 256 and it gets lower and lower.
Oh and Cigars
Onyx Reserve
At $3 a stick when you buy it in a box. It is a great deal for a very enjoyable maduro.
Bic Lighter
You could spend $100 on a nice lighter, or spend 50 cents on a Bic Lighter that does the exact same thing a $100 lighter does....that's light up your cigar. If this isn't a best bang for your buck, I don't know what is.
Xikar/Zino Cutter
These 2 cutters run you about $35 each. They are both considered the best bang for your buck in terms of cutters with their lifetime warranty and self sharpening blades ensuring a perfect clean cut each time.
Hope that was helpful guys.
