Zappo, as u said, i have chalked down Intel Core Duo, but these are also available, which one do u recommend?
1. Intel® Pentium® M (370-780)
2. AMD Athlon™ 64 with HyperTransport and Dual Core Technology(FX-60, X2 4200+ to 4800+)
3. Intel® Celeron M(370-780) Processor
4. Intel® Pentium® 4 (630-670) Desktop Processor w/ HT Technology 800MHz FSB 2MB.............These P4 Desktop Processors have the greatest MHz and GHz compared to all the other Processors!!!! MAX : 3.0 to 3.8 GHz
5. Intel® Pentium® M (730-780) and the Celeron M370
6. AMD Opteron™
7. Intel Core Duo Some Basic Questions:
1. What is the optimum GHz to be taken???
2. What is a Cache? (L2 Cache)
3. What is the optimum MHz??? Zappo told 8xx, but here many have 533.
4. What is the optimum Warranty to be taken?
5. NVidia® GeForce™, but which 256MB or higher?.....There is even the ATI Mobility™ Radeon®, and its much more expensive than the GeForce....but i guess GeForce is the ultimate...what say?
Please answer all questions

alienware systems are good but not recommended if u need to use it in India. It will be more than a headache to get them. look good but same models are available with
www.pctorque.com ( resellers for sager and administrators for
www.notebookforums.com )
Intel pentium M( many know as centrino processor) is good but now completely outdated. Intel core duo is nothin but two pentium M cores joined togather. Many say intel is better performer per clock compared to Turion but turion beats centrino is price per performance. 64-bit which is a compulsary necessity for windows vista to run is supported by turion but not centrino or core duo(yonah). And additional plus is the hypertransport with turion while intel is still using the crippled FSB technology. core solo is just a updated pentium M.
amd athlon or athlon x2 are desktop cpu's . My R4000 is running on socket 939 amd athlon 4000+ desktop cpu and believe me they are heavy and ugly.
The current performance king is the 19" amd lappie available with sli nvidia or ati crossfire dual gpu. second is the 9750 which is again bulky 17".
Many unknown people will say that celeron M sucks but the truth is that celeron is based on the pentim M itself with lesser 1mb l2 cache and lack of speedstepping technology. Much cheaper than pentium M's and certainly worth a buy intead of pentium M. battery life wont be the same if u are carrying it in standby but from start to finish u wont notice much diff between the pentium M and celeron. performance takes a beating due to lesser L2 cache but u can get the highest clock speed cpu which will satisfy what you need at half the centrino's price. and anyways in a graphics intensive application its the gpu that does 90% of the work and not the cpu.
pentium 4's with 64bit extensions only gain the 64-bit extensions along with 2 mb l2 cache instead of the older 1mb. the longer pipelines cripple the performance a lot and the performance by clock sucks. Cpu's are expensive and laptops carrying these are less in option and bulky. look at the asus 15.4 with nvidia 6800 (asus z81sp) or sager 9890(alienware,voodoo, abspc, hypersonic-pc etc options available too). They get too hot and certainly not equivalent to Amd desktop counterparts or intel and amd mobile counterparts. not at all recommended. I didnt believe this when I was a noob but a 2ghz turion or intel pentium M can beat a 3.8ghz pentium 4 easily. this is due to the longer pipelines and low l1 cache.
amd opteron is a server cpu and hence not in consideration here. But fyi it beats intel xeon which is in direct competition in all the tests by huge margins.
core duo is covered in along with pentium M.
If u are not in a hurry then wait just for 3 months. turion x2 dual core and intel merom which is a real dual core are about to be launced. both are 64-bit. Merom will supposedly have 4mb l2 cache while turion will have 2000mhz fsb along with 2mbl2 cache and lower wattage. Both will be manufactured with 65nm technology.
there is not specific ghz clock count that affects performance in each cpu.
In pentium M u should atleast go for 1.86 (wont run xp64 and windows vista 64-bit)
intel yonah 1.83 is enough for your work
amd turion doesnt have a comparable cpu but 1.8 is slower while 2.0 is faster. 1.8 will do the job but 2.0 is recommended which is cheaper than intel mobile cpu's
celeron m430 is the top of the line cpu from intel and is prices lower than both turion and pentium M.
a cpu has 2 kinds of cache memory or Random access memory for the cpu. L1 is the instructions cahce while l2 cache is data cache.
here by mhz you probably mean the fsb speed. Intel uses the front side bus or fsb technology for this which is obsolete. their highest cpu the extreme edition desktop cpu runs at 1.66mhz. p-4's with 64-bit set run at 800. new pentium M yonah cpu's run at 667mhz while older sonoma and dothan run at 533mhz and 400mhz respectively. Amd uses a new and better technology called hypertransport which uses the FSB to full effect. The amd mobile cpu's run at 1600mhz while the desktop counterparts run at 2000mhz.
dont go for extended warranty unless you have money to be spent. I had a 1year warranty which has expired. Hp mailed me an extended offer recently which I didnt take up as I dont find much value at $200.
nvidia is not good for notebooks as it takes up more power than ati. But nvidia performs better too. look at the ati x700 or x1400,x1600 or x1800. x1400 will be just about suffice. x1600 will do better. X700 is enough while x1800 will blast everything out of water.
If u still want to go for nvidia then look at nvidia 6600 or nvidia 7800 or nvidia 7600.
