latitude E6530 i7 3540M ok for "lite" video/photo work?

After much procrastinating, I took the plunge at the Outlet and picked up an E6530 with an I7 3540, 8 GB RAM, NVIDIA GPU, FHD screen. Most of my use in Internet, word processing, iTunes, photo editing (PSE, not CS6). I have also done some video encoding/editing via Windows Movie Maker on my 2 1/2 year old work desktop (Vostro 460 i5-2400 3.1 GHz, Intel integrated GPU, 10GB RAM), mostly Mini DV tape home movies, but some stop action animation for my 9 year old's Lego Wars projects. I plan on eventually getting a more HD type camera for movies, but nothing heavy duty as far as video work...just home movies and the like where it'd be mostly conversion, not a lot of editing.

I would have sprung for the i7 3740QM, but they don't come up often with the other features I wanted in m price range, so I decided to get it over with and get a i7 3540M configuration. I'm hoping to have this laptop for a while and sure the 3540M will be great for all the Internet, Word type tasks for a while to come, but do you guys think the DC i7 going to feel that much slower than the quad for the type of photo/video work I do? I have 21 days to find an Outlet i73740QM with my other specs and as the E6530 is phased out. Don't know if I would have to eat the 15% restock if I return it unopened for an exchange, and hate the idea of the exchange hassle, but I can upgrade just about everything in the future but the processor ;-).
Thanks!

 

It's already probably overkill for what you are doing.

 

Think the i7M dual core would feel much slower than my desktop's slightly higher frequency i5 quad for video/PSE?

 

Yes, it will be about half as fast as your desktop CPU. I moved from 3360M to 3840QM and the difference is more than 2x. Is it still possible to do all your work on a dual core? Yes but it's definitely going to take longer.

 

Does the E6530 having a dedicated GPU vs my desktop using the last generation integrated graphics bring them a little closer in speed? I always thought getting the NVIDIA GPU would boost video type work speeds. I honestly won't be doing a lot of video work, just don't want to hate doing any.
