NO, 6150 is not good for HTPC....at least m2npv-vm is terrible choppy for sport....for usual video it is sufficient
Source: http://www.hothardware.com/printarticle.aspx?articleid=935Running at full load, the MSI K9AGM2 consumed 10 less watts compared to the nForce 430/6150 series board and 2 watts below the 430/6100. When running idle, the 690G weighed in 6 watts less than the 430/6150 and 8 watts less than the 430/6100. This variance may seem small to some, but the best way to look at this is in percentages. When running idle, the 690G consumed close to 8% less power than the 430/6150 and 11% less than the 430/6100 based board. At full load the power consumption difference is closer to 7% less than that of the nForce 430/6150 based board, where the reduction was closer to 1.5% compared to the 430/6100. These aren't exactly make or break differentials obviously but notable none-the-less.
