4.Vram usage on some demanding games.It would bust some myth i guess
i *really* like #4
Using the GTX 680 and HD 7970 at 2560x1600 and 5760x1080 with enough AA to really tax them
- can also compare with the GTX 580 ... 1.5GB vs 2GB vs 3GB .. for high end cards.
- maybe toss in GTX 460 SLI to compare a 1GB framebuffer
And here's where detailed benches like FC2 (and even Source Engine and Street Fighter IV bench as well as synthetics .. and BF3) can be very useful. And i'd say that no more than ten games are necessary to find the trend and to draw conclusions.
