We've already had a look at one GTX 460 today which came from MSI. That particular version was a 768MB card and while you might be thinking that the 1GB is much of the same thing, you would be mistaken.There's more to the 1GB model than just a bit more memory; instead NVIDIA has chosen to bump up the specifications in some key areas. We'll get into that in just a moment, though.Since the GIGABYTE card didn't come full retail, we'll be getting stuck straight into the card itself. Once that's done we'll have a look at the specifications of this model and also how it differs to the 768MB version.This is also another OC version of the card, so let's see how GIGABYTE has chosen to mix it up. Let's not delay any longer and get stuck straight into it.
