"and no I don't wanna see my system lag when I run multiple programs at one go so I'll take something more future proof"

Unless you get a great SSD, the HDD is going to be your bottleneck (permanently). Don't think about 1 year later, even brand new, the laptop is not going to be blazing on multitasking just because you have Core i7-720/740QM (if you have Core i7-920/940 that's a different story).

There's just too much hype on Core i7. This is what led to a possible overproduction of i7-740QMs, which disadvantages users like me. Remember that Core i7 quad only runs 4 cores at the base speed, the highest clockspeed it can reach is only rarely reached, and it only does that for one core. For 1/2 cores it will go 2.53/2.66 GHz, and unless you are a CPU-intensive user, it will rarely use 3/4 cores. Often it turbos to about 2.0Ghz for 2 or 3 cores.
