With 32 bit game, the more VRAM you have, the less important board memory becomes.
I think maybe 2GB of board RAM and 2GB of VRAM, or 1GB of board RAM and 3GB of VRAM, so on and so forth..
But I often wondered if resolution and AA related VRAM footprint don't reside inside the games .exe?
Sorta, the mainboards memory has much (comparatively) less latency than the GPUs memory. IRRC, Skyrim is a large address aware game - and if I'm wrong there is a patcher that makes it a large address aware game out there. --- I think I'm the only person on gamefaqs with a daughterboard - ToastyOne New with a moderation history more plentiful than karma. - Fossil (Moderator)
