Help with RAM Please?

It depends on what operating system you are running if it is windows 7 32 bit you need 1 GB ram to run that and then the max ram can only be 3 GB so you will be waisting 1 GB and then you have 2 GB ram for the other things if you running and if you using 64 bit it needs 2 GB ram to run so you still just have 2 GB so you should get at least 6 GB plus if you run 64 bit if you want to benefit so i will advise you to get 2 x 4 GB ram so you will have 6 free for other programs and really its more the graphics card then the ram but your card is okay but find out if the card is 128 or 256 or 512 bit that is more important then how many GB the graphics card has you may have 1 GB but if you have 128 bit it will be to slow to even use that 1 GB look at bit. if you want more advice ask me i built me a pc and its doing good he he.
