From what you say, it sounds like it would be right for my purposes, but I prefer to ask questions rather than being sorry. The main reason that I focused on this card is because it has 2GBs of memory, rather than only 768MBs like the card in my desktop, which I'm hoping might have a good effect on a problem that I'm having with one program, which sometimes complains about being out of memory. I really don't know that the memory in question is that of the video card, but since I can't find any other problems, I have a hunch that it might be.
Actually, I don't intend to put this card in the HTPC, I will swap the current desktop card for it and put the new card in the desktop. The only thing that I've read that isn't quite right is that this card is for PCIe 3.0, and my motherboard is 2.0. The things that I've read said that the adverse effect is negligle, and if true it shouldn't be a problem for me, but if it could be a problem for anyone, it would be me.
