Due to the increased amount of inexpensive processors available have been comparing the i5-2520m and the i7-2620m for this laptop, presently have the i3-2350m and have seen the K73 advertised with the i5 cpu. The spec differences are mostly the secondary cache size on the i7. All three cpu's use the DDR3-1066/DDR3-1333 memory and share the G2/rPGA988B socket, So What Say You Guys.....will the i7 work and if so maybe the i7-2640 @ 2.8GHz, that would be fun to experiment with, they have gotten reasonable, for the techies' the motherboard is #60-N3YMB1100-D04. Thanks bunches for any imput or ideas.
