Hi sifus, i have a problem trying to find a new laptop for doing Adobe graphic software and sometimes movies with good audio

. Not really into gaming

. So far my options are
Acer
V7-582PG-74508G52k, i7-4500U + Nvidia GT750M + 24GB mSATA + 500GB HDD + (1920x1080 IPS; touch)@RM3399[2.2kg], 8GB, W8
(Very good display IPS which i like because i am into graphics and need good screen

)
Dell
Inspiron 15 7000, i7-4500U + Nvidia GT750M (GDDR5) + (1920x1080; Touch)@RM3599[2.6kg], 8GB, 1TB(5400rpm), W8SL, backlit keyboard, 58Whr
(Havent seen this model because cannot find it anywhere

but saw the video and it looks nice like mackbook. I saw the new boucher that this model with dedicated Nvidia GT750M is not full HD resolution but the online Dell shows it is full HD

. Can help confirm this model is full hd or not and is the screen anygood compare to Aver V7?
Lenovo
Y510p, i7-4700MQ + Nvidia GT750M(GDDR5) + (1920x1080)@RM3399[2.7kg], 8GB, 1TB, W8, red backlit, swappable ODD, 120w psu, 2 yrs
(Saw this model yesterday at 1 utama and it is selling at RM3099 already

. Seriously thinking to buy it but the RED keyboard is really irritating and dont know is this better then the MSI GE60-2OC.
MSI
GE60-2OC, i7-4700MQ + Nvidia GT750M(GDDR5) + (1920x1080; anti-glare)@RM3599,8GB, 750GB(7200rpm), W8, steel series KB
(I dont know this brand until recently researching it and this model is by far the most safest in terms of performance and after sales service

. Heard many good things coming from MSI user so included this into my list.
Overall this are the laptop i am taking into consideration

. Actaully what is the different i7-4700MQ and i7-4500U? And does the above 4 laptop i listed have Nvidia Optimus because heard that with Optimus the battery life will be longer. Sorry for such a long question

. Planning to get one new laptop on the PIKOM PC fair now have to really survey and not buy the wrong laptop. Thanks in advance
