… WOW… quick replies!!! You guys are awesome!

this seems to be the only card I can put in my machine (see attached) will it do the job?

…. JUST MISSED YOUR REPLIES… OK… I'll take care of it… Thanks for your Time!!! (sure I'll be back in the future)

… and I forgot to add… it's activated and Cuda window looks right (I'm an old guy not very computer savvy)…
loaded the DemoSuite files in Standalone and the nodes, interface info is there visually (on left side and right) but widow is black also… same as plugin window… also forgot running LW 11.6

just purchased Octane today… everything seems ok but NO Object in preview window (standalone and plugin) Mac Pro
running OS X 10.8.5 | GeForce 8800 GT and I downloaded latest Cuda Driver 6.5.14… am I missing something?
