I think I'll keep the 8800s there. With the coming of the 9900 series in 3-4 months, I don't think I'll bother with the 9800GTX and probably the GX2.
Maybe instead, I'll put up options for multiple graphic cards. So under 8800GTX in the high-end, I'll put like 9600GTs in SLI, 8800GTs in SLI, or HD3870s in CF. And maybe categorize that under recommended resolution settings, for those certain graphic setups.
