Help me choose a laptop please

Hello,
This is gonna be my first laptop ever and I need it to be powerful enough for casual gaming, a lot of word processing and photoshop works and also some video decoding.
Unfortunately, here in Iran it's really hard to find a decent laptop with a logical price due to the difference between currencies. Any way I've done my research and now am stuck between these 4:

MSI CX 61:
i5 3210m - GT 640m (2 GB DDR3) - 4 GB DDR3 - 750 GB (~ $805) w/ i7 3610qm (~ $950)

Dell 15r 5520:
i7 3612qm - ATI 7670m (1 GB DDR3) - 8 GB DDR3 - 1 TB (~ $855)

HP DV6:
i5 2450m - ATI 7690 XT (2GB DDR5) - 4 GB DDR3 - 640 GB (~ $755)

Lenovo E530:
i5 3210m - GT 630m (2GB DDR3) - 6 GB DDR3 - 500 GB (~ $750)

Acer V3:
i7 3610qm - GT 640m (2GB DDR3) - 8 GB DDR3 - 750 GB (~ $900)

The resolution for all of the above is 1366x768 (all 15.6"). I do translation works mainly, so my heaviest multitasking will usually consist of 4-5 dictionaries (some of them really resource consuming) + word, excel (office 2010 in general) - As for gaming I can live with medium (if not high) details for 2012 titles.

Edit: added the amount of VRAM.
Edit 2: added Acer V3. I'm CONFUSED!

Thanks in advance.

Thanks to this wonderful forum i made up my mind.


MSI CX 61:
i5 3210m - GT 640m (2 GB DDR3) - 4 GB DDR3 - 750 GB (I'll be adding another 4GB RAM + 128 GB Intel SSD)


i7 is just too much processing power for me.
