I have an ASUS A52JK which also comes with Intel i5 430M CPU. The same laptop also comes with other types of processor, which are:
1) Intel i5 430M/450M/460M/520M/540M CPU
2) Intel i3 330M/350M/370M CPU
3) Intel Pentium® Dual-Core P6000 CPU
I am thinking of upgrading the CPU of my laptop to Intel i7 940XM or i7 640M. I have checked the TDP and CPU ID for Intel i5 430M, 640M and Intel i7 940XM. The TDP for i7 940XM are higher, which is 55W while the TDP for Intel i5 430M and 640M is 35W. The CPU ID for Intel i5 430M is 20652, the CPU ID for Intel i7 540M is 20655 and the CPU ID for Intel i7 940XM is 106F1.
After reading the successful stories from the first link that I give above (and ignoring the unsuccessful stories :P ), I feel like I want to go for i7-940XM. If i7-940XM doesn't work, then I will try i7-640M (or lower). If the i7-940XM, works but have overheating problem, then I will try the i7-840QM (or lower).
