I wanted to add a comment to this because Marcum seems to have been getting some flack lately with people having issues getting responses from them. I have a feeling the reason they were having issues was how they contacted them.
I went to the website and sent an email to [email protected]
This generated an automated incident within their ticketing system which I received that email immediately. I sent this on the weekend so didnt expect a response right away Monday, but sure enough, my ticket was commented on Monday where they inquired about whether it was still under warranty etc.
I told them it wasnt and he replied again within an hour or so and gave me all the lowdown on what I needed to do, how much it would cost and how long it would take.
He didnt answer my question as to whether it was the graphics card itself, but they go through everything for a flat fee. I havent sent it in yet because I wanted to use it the rest of the season first, but I was happy with the quick response to my questions.
