so if i were to get the 670, do you think i should also get 8GB of RAM instead of 4? How much does RAM affect gaming?
IMO if your getting 50 - 60 FPS and you upgrade the GPU and get 120 FPS your not going to see the game play any differnt!!!
4 GB of ram for gaming is fine. you wont see more FPS going to 8 GB
My i5 750 and GTX 560 plays any game out there
If you really want to blow 600 bucks sure a GPU and 8 GB of ram ( like the OP said whould be whare to put it )
