I would think each one would take up about the space of a typewriter . <| sep |> No problem , friend ! <| sep |> Big news on Fark . com <| sep |> More ram allows for higher quality textures . In theory 4 gigs could handle that aspect better . That said , it ' s a touch meaningless if the rest of the card isn ' t powerful enough . Card manufacturers throw on extra ram to inflate the prices of their card without incurring much extra manufacturing costs . A 730 would be a bottleneck keeping the 4 gigs from ever really mattering . The 750 ti is faster and will use the 2 gigs it has much better . Car analogy 4 gigs on a 730 is like 19 wheels on a Hyundai Accent . They make make it stand out , but it ' s still a pretty cheap car . 2 gigs on a 750 ti is like 15 wheels on a Civic . Maybe not as noticeable to a casual customer , but much better once you know what you ' re looking for .
