I'm looking at buying a 22in widescreen monitor that natively runs at 1680x1050. I'm also wanting to upgrade my current 7800GT to match. I'm trying to decide whether the 320MB or 640MB version of the 8800GTS is the best choice. I've never been one to buy a lower-end choice, but it will be stretching my budget buying both a GPU and monitor. And if there really is no foreseeable difference, then the choice seems obvious.
The VGA charts actually show the 320MB 8800GTS used as (barely) outperforming the 640MB, in some cases even in 1920 resolutions. So no real answer there (or maybe there is?) I'm just curious if and when the memory difference becomes an issue. I'd definitely like to know if it will be an issue at 1680x1050 (I suspect it won't), but I'm also curious how high you have to go to see a significant difference.
