Last response: in CPUs
Both are about equal actually, so go for the i3 as it draws less power and its socket has upgradability.

'was gonna say, the Core i3 has an integrated memory controller (like the Athlon 64's did) and PCI Express v2.0 support on the chip itself, which will improve the overall performance of the system far more than losing 9MB of overpriced cache memory from a die shrink that is a decade old when manufacturing costs were wayyyyyy higher.
12MB of cache doesn't have 4x times the hit ratio of 3MB.
- It might in fact only have 1/4 the miss ratio however....
Still if the miss ratio is 1% on the 12MB part, and 4% on the 3MB part.
- The hit ratio is 99% on the 12MB part, and 96% on the 3MB part.
So if the Core i3 is clocked just 3.125% higher, it will outperform the 12MB cache part.
- The memory interface on the Core i3 is 21GB/sec, so in effect the RAM itself almost is a level of cache, when compared to a Core 2 Quad which uses the old-school Front Side Bus technology, which is half as fast (tops) in this case.
