Thanks for the tip. To be honest, I bought the replacement parts a
week ago (AMD A8 6600K, 8 GB RAM). I've installed Linux Mint 16 64
bits, and I ran benchmarks from "HardInfo" utility and compared with
my laptop running Intel Core i5 460M with Linux Mint 16 32 bits. For
most tests, the AMD is faster (in some of them, more than 2x faster,
others about 20-30 %, and for N-Queens it is actually slower).

Regarding Java performance, I'm using JDK 7u51 in both systems (64 vs
32 bits); in the AMD I'm using NetBeans 7.4, in the Intel I'm still
with 7.3.1 because I had some issues with 7.4. Again, most of the time
the AMD system feels slightly faster (hard to say, maybe 25 % faster),
although I've also hit a couple of times a 2-seconds hang while
editing GUIs in NetBeans. Still testing, but overall I'd say I've got
better performance for not much money and a FM2+ motherboard prepared
to switch the CPU for a newer, faster one in case I need it.

Thanks again for replying.
