Huge disagree, your bleeding beyond the NF4 Chipset and 939 socket interface here. AM2 was out a year before crysis. I tried to running 2 x 6600GT's in SLI back in the day and I upgraded to a single 6800 GT because SLI was such a headache.
That's some serious rose colored glasses, the first rendition of SLI on NF4 was plagued with driver issues, Microstudder or just non support. not to mention it only had the same bandwidth as AGP anyways. only 8x Bandwidth max. Hard pass! A single PCIe slot useage was just fine, but there was no...
Best 939 mobo?? I think not! doesn't even have AGP, but hey I'm a little biased. :D
I actually have the much more rare AGP NF3 Ultra 939 DFI Board, in my possession and I believe its one of if not the only AGP board to support 1 & 1.5 Cas latency memory.
Its been up for about a week, lots of traffic, but still not sold. Not mine, For sale in Germany/Europe, no shipping to USA so it seems.

Geforce 3 Ti 200 is my #2 favorite of all time, I had mine for much much longer than it should have ever lasted. I think I begrudgingly replaced it when I was forced to upgrade to DX9 for BattleField 2 but even then I kept it in a box for almost 15 years. That's how much of an impact it had

Not a particularly sexy model, but still interesting none the less. Engineering samples in any form are quite rare no?
Cheers,
