I'm just wondering whether it's worth it for me to get a discreet graphics card at all when I have so much regular ram.
I guess I'm wondering whether my computer will be able to tap into the regular memory when it needs it for graphics. If that is possible it seems to me that getting a 1GB graphics card won't be worth it because I will always have spare RAM (out of the 8GB of regular ram).
hmm... good question. Well any computer needs some sort of GPU in order to even output anything to your monitor. I suppose I am partially wrong in that there is shared RAM that is used both for the CPU and graphics to use, but really for RAM it’s only a matter of having "just enough" and having more is just overkill, for lack of a better word.
I guess essentially if you had your laptop with 4gb, 8gb, 16gb, 32gb, or an infinite amount of RAM, it won’t make any difference in terms of your graphical performance/FPS.
I don't understand the question. GPU stands for graphic processing unit. The whole point of it is advanced graphical processing for things such as games. You will have a GPU it's just very weak and intended for 2D processing. If you want to play any modern 3D games you will need a decent card. If not then the IGP will be fine.
I agree with rolli59, jyjjy and the others that posted here. More RAM will only help with things like how many internet browsers you have open or word documents, basic everyday things you do with a computer. Having a GPU/more powerfull GPU will only help with being able to play games/3d rendering on that computer. Two different parts of a computer that do two different things.
I think you're getting confused with graphics ram and system ram. Graphics processing units require much more bandwidth than CPU's therefor the ram included on a discrete (hookers are discreet) gpu is much quicker than the system ram. You buy a gpu for improved graphics, not for the ram. A lot of discrete GPU's that have their own ram also use the system ram in case more is needed. However, this rarely increases in-game fps as the system ram being used for graphics takes longer to access. So as others have said, get a graphics card if you game. Otherwise its not necessary.
No doubt that is a stronger graphics chip it the laptop. But... I don't think I have seen a laptop where there is a provision for adding or replacing a stronger graphics card. I think there may be some external boxes that can include some sort of better graphics processing. If gaming is a high priority, then the OP should look for a laptop that comes already equipped with a strong video card.
