I am looking at buying a new CPU for my laptop. The two that I am looking at are slightly different and I want to know which way to go. The first is an Intel Core 2 Duo 2.2 GHz with 2MB of L-2 Cache. The other is an Intel Pentium 2.3 GHz with 1MB L-2 Cache. Is the processor speed needed more or is the L-2 Cache the thing to go for in this decision. Please help me.
