Listen, overclocking is like turboing a stock motor. I overclocked my celeron 1 gig a while back. It bent over and took it in the ass, but I blew my motherboard. I'm now running a p4 2.4ghz on a soyo p4x400 dragon platinum edition mb.

You'd have to understand chips in general and binary to understand the AMD x P4 argument. See P4's have a math coprocessor. This allows it do to complex math MUCH faster than an AMD, not to mention the fact that windows is built to work with intel CPU's, since ALL computer processing is math and a hybrid combination of AND and OR logic statements.

Games get better performace [if you really believe that, I believe that is more about your RAM and video card, I'll explain] on AMD because they don't have co-processors, they use processor cycle on regular functions, and can do things like transfer memory [ie, blitter images onto the video ram] faster. Now the better your video card and the faster your RAM, the faster and more space your computer has to create frames and blitter [transfer] images onto the primary video buffer. AMD also calls it the AMD XP 2400+ and it's only rated for like 2.0ghz, search more online for details about that.

Think of it this way. Do you want to go through the backache of getting adapters, shift linkages, axles, and wiring for a b18c1. You could get the same performance from a b16a with internals and intakes and it would drop right in and you'd be less likely to have a problem.

Games do not use math anyway. I know that may seem contradictory, but small consoles like game boy can't handle the math. Programmers of games use a trick called bit shifting. See multiplication could take several processor cycles to compute. Addition and memory commands take one cycle.

ycoordinate * 6

that may take several cycles to compute. But if you shift binary bits, once to the left halves the number and once to the right doubles the number. 100 =1 | 010 = 2 | 001 = 4. So break down ycoordinate * 6 into it's binary factors.

[>> means shift bit to the right, << means left, it's actually reversed because binary is backwards, but I don't want to confuse you]
6 = 011, y = 3 or 110
3*6 = 18

6 in exponents of two = 2^1 + 2^2. y*6 therefore equals
(110 = 3)
(110>>1) + (110>>2)
+01100
+00110
=01001
= 18!!!
TADA!!! no multiplication involved

This can complete in one cycle because it involves memory shifting and addition. Pentium or AMD your games will function the same, because programmers try to stay away from math functions like divide, multiply and powers because they can shortcut it to make games faster. So it's really about what ELSE you do with your computer. You'll never find an AMD in a high profile server or mainframe [non-80486 stepping family of processors] because they just aren't reliable. Pentium kicks ass at numbers. AMD doesn't, and for games why would it? In the home PC, it's really about your motherboard bus size, hard drive buffer size, and amount of RAM. How fast would a viper be if it only has 1st and 2nd gear? You're only as fast as your slowest component. Don't worry about processors.
