Let's say you are given 2 options :
A. Intel Pentium Dual-Core E2180 (2.0 GHz) + Biostar P35D2-A7 (total price: RM525)
B. AMD Athlon X2 5200+ (2.7 GHz) + Biostar TA780G M2+ (total price: RM495)
If you choose option A because you heard people say that Intel rules and AMD sucks, then you are half right. The reason is that Intel really rules......IN THE HIGH-END(RM 600++) section, while AMD sucks because they can't compete in the high-end. But that does not mean that in the low-end(RM200~350), AMD still sucks.
Option A and B, both their performance are almost equivalent (see this, the 5200+ and E6420 you see are 2.6GHz and 2.13GHz respectively, try to gauge the performance yourself). But the difference is the motherboard. While both MB(motherboard) are almost the same price, the AMD MB sports extra features, like an integrated graphics card and smaller chipset die (55nm - means less power consumption).
Not to mention that AMD MB can support next-gen cpu while Intel cannot. Intel likes to change their chipset cpu support every year, so the Intel MB you bought this year might not be compatible with the cpu that released next year.
So it all boils down to choices, whether you prefer AMD or Intel.
Remember, this post is for the non-overclock, average guy. If you are an overclocker, stop telling people to buy Intel cpu because they overclock better, NOT all people understand or want to take the risk of overclocking.
