My money is on 4 cores still being enough for gaming 3 years from now, I can't see needing to change my Q9650 any time soon at least.
That's fine but we are helping nitram100 spend "his" money . . . we have to try and put ourselves in his boots and help him decide what would be best for him . . . I agree both processors are good but for the small premium involved I think the X6 provided a tantalizing prospect for someone who wants to sit on a system for several years . . . one has to "speculate" what the future will bring in terms of MultiCore gaming . . . one has to also "speculate" if nitram100 will move onto other processor intensive tasks beyond just gaming . . if so then the additional £35 premium for the X6 becomes easier to "justify"

. . if not and the system is to be used for gaming and only gaming then perhaps this £35 can be kept in his wallet or spent elsewhere on the system?
You mention you own one of the finest LGA775 processors on the planet (Q9650) which afaik was released about two years ago (Aug 2008) . . . I'm sure back then there was a similar thread to this one weighing up whether or not the premium for the QuadCore was "justified" over a DualCore Wolfdale . . . although the premium for a Yorkfield was probably a lot more than £35.00 . . . as can be seen by the latest MultiCore games having more than a DualCore can prove advantageous in the latest demanding titles . . . wonder what the story will be in a few years time? . . .
Also I've seen plenty of people change their mind about overclocking, and the black edition will make things easy peasy if you do decide to try it later on.
I agree it would be almost criminal to not overclock a black edition chip but then again the same can be said about the X6 1055T which if used on an AM3/DDR3 platform would be fairly easy also to overclock albeit using the Ht Ref.Clock instead of simply upping the CPU-Multi . . . although this is all another moot point if nitram100 will not be swayed about overclocking . . .
Thanks for any more info guys
Martin, I think both processors have their own advantages and you would need to check several reviews to really get a better ideal of which was right for you according to your "personal" buying criteria . . . the point I am trying to make is that while today both processors do the job you need them for "perhaps" the X6 1055T will offer you a better investment in the long-term? . . . I say "perhaps" as none of us know for sure what the future brings in terms of MultiCore gaming . . . if four cores is all the is still needed for optimum gamplay in two-three years then the X4 955 would certainly seem a wise choice (and saves you £35 today) . . if however we see more and more modern games making better use of the extra cores then it may be the X6 proves to be the better investment in the long-term? . . . I guess it really depends if your not gonna upgrade for several years and if this £35 premium is something you can afford or not?
I would be interested to see a multitide of gaming bench data comparing the two chips, I would have thought for older games that only utilized 1-3 cores the X6 1055T would have been faster as the TurbCore function "should" boost the processor frequency up to 3.3GHz which is faster than the stock speed of the X4 955 (3.2GHz) . . . although looking at the benchdata from Anandtech this doesn't appear to be the case? . . . either these games are using more than three cores or TurboCore is switched off or simply not working as expected?
I've included some non-gaming MultiCore apps not to suggest you get into Video-Encoding but instead to "possibly" demonstrate how games of the future that are well coded for MultiCore will react . . . if in a couple of years the games are coded to use these extra cores there sure are some nice gains to be had!
