Suggestions on New Mac Mini

Hi! I'm new to the forum, so a hello to you all!!

I wanna get a new mac, this is my first mac. But am having some trouble in getting a conclusion on which should I buy; so here I am.

There are two options in my mind:

Mac Mini 2.7GHz dual-core Intel Core i7 with 4MB on-chip shared L3 cache
4GB of 1333MHz DDR3 memory (RAM)
AMD Radeon HD 6630M graphics processor with 256MB of GDDR5 memory
1x 500GB (5400-rpm) hard drive

OR

Mac Mini 2.0GHz quad-core Intel Core i7 with 6MB on-chip shared L3 cache
4GB of 1333MHz DDR3 memory (RAM)
Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory
2x 500GB (7200-rpm) hard drives

I'm going to use the Mac Mini for:
- Basic Stuff (Pages, Keynote, Numbers, Chrome...)
- Full HD Video Editing (iMovie/Finalcut; Exclude special effects)
- Full HD video playback without lag
- Playing Games (Things like New Super Mario Bros, Super Mario Galaxy 2...) via Dolphin (See http://goo.gl/vvPoV and http://goo.gl/j7apu for details)

Please assist me in deciding my new Mac Mini. Any replies will be appreciated.


PS: I'll be connecting to a DVI (1680*1050) display usually, sometimes HDMI (1920*1080) display, but never Thunderbolt (2560*1400) Displays

Will the difference between 5400-rpm and 7200-rpm be a huge one?

First of all, thanks for all the prompt replies!

The things you're planning on doing will not stress the 3d subsystem at all, but you will see a benefit from more cores in productivity type apps.

Actually may I ask what type of tasks will stress the 3d subsystem?

WELL the 7200 rpm drive is faster

May I ask by how much? Is there significant difference when I'm doing tasks mentioned previously?
