yes
Better or worse, it depends.
Buy the core 2 duo. It's faster newer, better. Don' be confused by the Mhz war.
Intel centrino-dio is better for the current market.
The Core Family
It depends, but usually Intel is better. Older AMD processors (compared against the early Pentium 4) were much faster, however.
Celeron doesn't refer to any particular processor series. Celerons were cost-reduced versions of their Pentium equivalents. The Celeron in question could be based on a Pentium 2, Pentium 3, Pentium 4, Pentium D, or Core 2 Duo. In which case the answers would be "Pentium 3, Usually Pentium 3, Celeron, Celeron, and Celeron", respectively.
AMD anthlon x2 dual core. AMD has more quality. Much faster and hold more space/memory. INTEL are OK, but bad. anything AMD is ALOT better!
Centrino = better perfomance, less heat and less power consumption. The centrino is based on the newer Intel Conroe architecture.
You can find benchmarks on tomshardware.com, to find out exactly which processor performs better for the games you'll be playing.
The 3.2 GHz processor is slightly better. Please note that all 3.2 GHz Pentium 4s support Hyperthreading, so the 3.2 GHz isn't in any way disadvantaged.
That depends. Centrino is more of a technology used on processors, rather than a processor itself. Look at the actual processor type when you are looking at the specs. if it is a Mobile Pentium, the Athlon 62x2 is a better processor in most cases. However, if it is anything from the Core Duo or Core2 Duo line, they will be better than the Athlon in most cases.
Pentium D is a dual core processor, while the Pentium 4 HT is a single core that is capable of running two software threads. More simply put, The Pentium D is 2 people each pulling their own wagons, the Pentium 4 HT is one person pulling 2 wagons with lubricated wheels. Over all, the Pentium D is better because it is truly dual core, although the Pentium 4 does a great job of trying.
