The AMD platform is not cheap enough to justify going that route.
In general, you are going to spend about 175$-200$ on a motherboard for the 1055T, plus the 200 for the chip, puts you at about 400$
i7 860 is a 300$ chip, you can get a P55 LE (evga) for 110$, putting you at about 410$.
In general the i7 is going to be much faster in standard applications, worth the little bit extra that you are going to spend to go that route.
Why are you are suggesting a top of the line motherboard for one brand and a budget motherboard for the other brand?
