Is an Dual Core enough for GTA 5

Hard to say, I heard many people have problems with gta5 on laptops.

Maybe, if that's your thing.
I hope you are not buying it for the game...

GTA 5 no...
GTA4 yes :D

it should be playable on lowest, I'm running it ok with 2120 i3, though yours is a little worse

look in youtube for:
Medion Akoya P6624 - GTA V Gameplay (i3 370m, Gforce 425m)

if he can, you surely can do better...

yeah it is :)

wowowow some ppl are saying yes or say no lol

I have Athlon II x2 245 3,14 GHz and game is running fine.

Don't buy a laptop for playing GTA V.

You may be able to run it on lowest settings 720p @30fps, but it won't be that enjoyable.

Tried it on my i5, 660M Laptop.

it will run ..look at this https://www.youtube.com/watch?v=mYYYtsHxCvc
and this https://www.youtube.com/watch?v=0aaDGf_Owmo

those two lower than the one u want..so make sure it will run

i5 is good enough for anything. GPU is what matters and looking at youtube it looks like it is okay.

My advice: get a better CPU (I don't like the sound of the specs of the iabcU cpus)
gt 840m ... I'd say you might want a x50m... If I recall correctly, my gt650m beats the 840m, might wanna check a benchmark
also, it's cheaper to get a 7200rpm HDD than an SSD, it's still fast enough for laptop gaming, and has way more space (just be sure it's 7200rpm)

how much $$$ are you investing? (and where, prices differ between continents)

maybe...... i seen it run in very low power PC's, so maybe :3

Depends on what dual core. I3 will do fine. i5 5200U will be completely fine for 30fps

I'm pretty sure it will. Also, if it doesn't, there's a super-low end mod out there. Just google it if you're interested. It runs even on a Intel Integrated Graphics with that!

dont use a laptop for games. this is what desktop pcs are for

Well, I run it fine on my laptop.
I have these specs:
I7-3537u
GT 740M
8GB Ram

I have all the settings on medium (= the lowest) and I play with a resolution of 1366x768, but it still looks pretty. I have 29-31 FPS constantly (I have locked it at 30, because of heat).

So the game runs fine for me, but I want to warn you that your pc may get very hot while playing, which would reduce the life-span. I recommend using a laptop cooler.

Good luck! =)

Based on this you should be good to go. So far their results turned out as reliable for me.

It should definetely be playable on low

you can run it, but i dont know which setting will have good fps, probably the lowest settings, with some settings on medium

Not relevant, but you should use "a" and not "an" before dual
"an" is for words that start with one of the followin: a,e,o,u,i.
or anything that sounds like that. for example: an R.
cause R = arrrr.
or an ambulance.
