    Seeing as recently we have discovered that we can upgrade our RAM from the standard 1333 Mhz to 1600 Mhz im just wondering if we can take a bigger leap forward in RAM!

    Is it possible to run GDDR5 RAM in place of the DDR3 ? i mean if the GPU uses it is the rest of the computer built for it? Does anyone know about this, because that would be awesome!!!

    GDDR is graphics double data rate RAM. It's independent from your chipset's memory. DDR5 isn't even available, yet. I'm careful not to say invented because I couldn't find an article but I don't believe it is.

    Bandwidth is not an issue for current CPU. DDR3-1333 is just fine. GDDR5 is based on DDR3 but use memory chips with graphic dedicated features.
