Desiibond - ur pick on motherboards isn't fair!
For Intel you picked P45 instead of P43 which is a lot cheaper, but then I thought its because, P45 is the one used in the BENCHMARK above mentioned. But if that was the reason, you should've picked 790FX board right? Not 780G!!! I guess it makes a lot of difference in Price???
SO again, NO COMPARISON BETWEEN Q8400 and AMD X940! Q8400 is still a worthy contender also considering the fact that the OP prefers Intel (like me).
Even I do the same thing, if the AMD outruns Intel only a SMALL difference in performance/price then I'd definitely go for Intel - won't mind spending a bit extra for INTEL logo.
And as in the case of VIDEO CARD, I've suggested the OP to go for ATI RADEON (which I don't like a bit) just because some of the models are way better in price/performance ratio.
4870 clocked at 770 (9k) is way better than GTS250 clocked at 738 (8.7K) - thats why i recommended him 4870 radeon.
But I'd still prefer the NVIDIA card - i know i'm dumb. But I like nvidia sitting inside my pc than some ATI s***!
