> Hello,
>
> I'm in the process of putting together a GPU workstation based off of
> a Tyan S8232GM4NR motherboard -- it's a dual-socket AMD G34, with 4
> PCI-e Gen2.0 slots that are spec'd to run at 16x
> (http://tyan.com/product_SKU_spec.aspx?ProductType=MB&pid=696&SKU=600000215).
> My two biggest concerns are:
>
> 1) the bandwidth on my motherboard with respect to the GPUs, and
>
> 2) which commercial Nvidia GPUs I should go with.
>
> From what I can tell by Axel Kohlmeyer's response to Matt Roark's
> inquiry (http://www.ks.uiuc.edu/Research/namd/mailing_list/namd-l.2011-2012/3416.html),
> you have to look out for motherboards with integrated "PCIe bridges",
> which I haven't been able to confirm on the S8232, either in the
> manual or from looking online. Does anyone have experience using this
> board for namd?
>
> Also, I noticed Francesco Pietra has done some testing with GTX 680s
> (which is what I happened to initially purchase), but I haven't seen
> much else on namd-l discussing these cards. Has anyone else had a
> chance to compare the 680 performance over the 580s? I've had a hard
> time judging the advantages of the new Kepler architecture over Fermi,
> especially in context of namd performance. Thanks for any help you can
> give.
