I have just pushed the experimental KC705 code to the repo.
Thanks!
I ordered my AC701 today. I'm playing with the eval software now. The clocks run a little bit slower than the Kintex line, but it has nearly as many DSPs as the chip you're using. I have high hopes for a minimum of 600Mh/s and shooting for 800Mh/s. Initial compile showing 92% dsp usage, 43% lut usage, 67% memory lut usage and a clock of 345mhz or so. Should be able to squeeze another core in there.
I was wondering, did it really take them 2 weeks to process & ship your unit to you after ordering? That's a big yes. They're not going to ship my card for 2 weeks after ordering

. Maybe they've got a large order queue? Maybe each card is made to order? no idea. Seems a rather long time to wait though.
AJR,
If you're going to get into it I would highly recommend you get the 705 or the 701.
