Looking at just the CPUs the 740QM has the advantage in most respects.
That shows up in the Passmark CPU benchmark scores:http://www.cpubenchmark.net/cpu_list.php
AMD Phenom II N950 Quad-Core = 2699
Intel Core i7 740QM @ 1.73GHz = 3618
The Toshiba has unusually good speakers for a laptop. A 7200RPM HDD better matches the rest of the overall performance spec of either system. But I don't think it should be a go/no go decision point for what you plan. Same for the CPU even with the fairly large performance gap between Phenom II N950 and i7 740QM. Both CPUs have enough 'grunt' to get the work down.
