Gainward has 512MB 7800 GT & 6800GS

GAINWARD decided to deploy a different tactic this time around. As it could not get any serious numbers of Geforce 7800 GTX 512 chips, it decided to make its own 7800 based card with 512MB of memory.

People do realise that the 7800 GTX 512Mb is faster than the 256Mb version, not because of the extra memory, but because clocks speed of both GPU and MEM are higher are on the 512Mb version.

if Gainward is only increasing the amount of memory on their cards, it won't show up in the performance charts.
