Replying to Computer geeks of NS, quick question - Processors

So basically im looking at getting a new laptop and i've found one i really like, and there's two options. one with an Intel i5-3210M processor and one with an i7-3630QM processor. i use my laptop for photo editing (photoshop and lightroom), general internet surfing, a bit of gaming and dj-ing (traktor scratch).

my general feeling is that the i7 won't make a huge amount of difference to me (it's also about £200 more for that one i think), am i right in saying this? sorry if this sounds stupid haha
