excellent, thanks for the response. i do understand the whole opengl for nvidia stuff, i just couldnt find a difinitive comparison between a recent single x1900 card and a cf setup. toms hardware vga chart is very outdated and i cant rely on that to compare either ati or nvidia counterparts because of newer drivers and such.
how about my other question, anyone know if 4gb of ram would be prudent? its pretty cheap to upgrade ram nowadays, especially ddr ram.
