It isn't what mobo to choose ( P35 DS3R regular or the C version for future expandability ), its what processor to choose
A few posters mentioned that the q6600 wasn't worth it and I read this article very throughly: Intel's Core 2 Duo E6750 processor - The Tech Report - Page 1
It contains some good information and come July 22nd the decision is kind of hard to make. In the benchmarks the q6600 really owns the e6750 ( prob cause the benchmark can take advantage of all the cores ), while the e6750 can probably overclock better ( someone mentioned the q6600 can only get to 3.2 ghz? ) and had reasonably better performance when it came to games. I'm mostly goign to use my high end build for games and not so much applications, but I'm wondering...is it worth it to just dish out the extra 40% cost ( 80 bucks ) to get a q6600? Will the e6750 even be 183$ come July 22nd or Sept 2nd?
I know most will respond saying that the q6600 is not "true" dual core and therefore isnt worth it, but no one really knows if the penryn will be that far ahead in performance, and thats at the very least 6 months down the road...I mean reasonably if I go with the e6750 ill have to stay with it for at LEAST 2 years, and who knows how many more games will use the dual core.
On the other hand, if the e6750 can overclock significantly better then the q6600 then I guess it would be more worth it...unless it wasnt 183$ on July 22nd..in which case waiting another month would be too costly...
