That's a bit faster.

However, the thing with graphics cards is that the first number is generally a year or generation (Erm, I'm not sure I understand the current AMD card designations). So the Gtx 950 is more or less the current version of the Gtx 750. Looking at a comparison website, I'm seeing it as something like 25% or 50% faster, which is not to be sneezed at, but it's not going to be a massive difference.

nVidia are about to announce high end cards tomorrow, those will be eyewateringly expensive.
