Go with 955 C3. IMO the extra bump in clock speeds for 965 are for those people who want a higher clocked processor without overclocking the chip. Some might argue that the 965 had better chip than 955 but in the end, overclocking would still depend on your cooling solution, ambient temps, skill, patience, and of course, luck.
Do yourself a favor and watch one of the following documentaries on youtube (they are in HD and full/legal uploads from the producers). And no, these are not conspiraciees and no they are not about 9/11 (I'm not saying 9/11 is/isn't a conspiracy however).
Fall Of The Republic
Our government is MUCH more corrupt than the average american knows.
I wont go into any details because it is so mind boggling you'll shrug it off like the average citizen(slave) when they hear something that doesn't go along with their perfect view on life/society.
P.S. The documentaries are based on facts which they show.
About 9/11. I believe the government knew about it (WTC 7, which was the smaller tower that fell hours later, was demolished with explosives).
I don't conclude it was all our government, but I do believe we need a full and complete investigation (both government AND 3rd party).
