Asus VGA GF7800GT/DUAL/2DHTV 512MB DDR3 PCIe

Asus VGA EN7800GTX/2DHTV/PCI-E 256MB 2DVI2VGA

I whas really wondering, what can a 512 mb graphic card do that a 256mb one can't do? Is the difference big? Because i want to buy one of them and in a few months dual run one of them =]. but the 512mb one is very expensive and i really would like to know what you get when you got a 512mb videocard...better graphics?

Not atm, I dont think there is any games that have that kind of texture load.. D3 is supposed to at Ultra Quality, but that is the same texture resolutions ,only uncompressed, as High, so it doesnt show much difference for it..
Cant speak on behalf of coming games tho, sooner or later someone will take advantage of the extra memory, its not really necessary yet, but perhaps comforting to have..
512Mb wont be faster tho.. not in current games atleast..

The 512 GTX is faster (edit: that is, higher clocks than the 256 GTX) so that helps and the 512 helps in some games like Battlefield 2, Quake 4 (ultra quality mode) and FEAR. In those games, it mainly eliminates the hitching but you also still need to have 2 gig of RAM to completely eliminate it.

Same here, A 512 card actually helps with some games to avoid stuttering and offers sometimes smoother gamesplay. Performance wise it will not help much unless the card itself is faster (IE GTX 256 vs 512)

The 512 he lists in his posts is the dual 7800GT, which doesn't actually have 512mb

Doom3/quake4 uses over 256MB of texture memory, BF2 does, and so does COD2.
