You won't notice the difference in gaming the lead role in gaming is the GPU which means = Better GPU Better gaming :) plus there isn't much difference between these two CPUs

Uh go with the I7 and the 740m there will be like a 1 to 5fps difference from the 840M but ya go with the better processor
as this I5 is only 1.6Ghz which sucks and is dual core which also sucks

Won't make much difference you could need a 4GB when playing games like Skyrim and games like that and 2GB for normal games like Batman Hitman and as these two cards cannot play on ultra you won't notice the difference of the 2 vs 4 GB

is there any possibility that 840m 4gb gpu will bottleneck i5 2.2ghz 2 core cpu??

On GPUs like this you're never going to use more than 2gb of Vram and the 4gb is just a stupid marketing gimmick because people assume that more is better. This is also why basically all prebuilt PCs come with 8gb or more of ram even if they have a $60 CPU and a system that would never even use more than 4gb of ram.
