so all i realy want to know is how much fps will i get

i Would say about 14-23 Fps on Far so that's not really that good , Considering my Pc which is maybe 3 times the price will be around 160fps , Try and laptop for a laptop with i5 then your Fps will be boosted up a bit , Dont look at the RAM ,i say if there if 4gb or more thats good for a laptop .

Not really windows 8 isn't good for games neither are inbuilt graphics cards

Thats a wierd deal. A year and a half ago I got a very similar model samsung laptop that I am using right now. It has the same specs as that one except mine has windows 7 and dedicated nvidia graphics. The strange thing is that mine, despite having dedicated graphics, cost only 300 in currys (I think currys and PC world share their prices)

My laptop can run minecraft at about 52 fps. I think thats down to the graphics though.
