Thanks Sajuuk & b-force for your responses. Spent more time looking around. Learning that the nVidia card I linked in the OP is just a rebrand/update of an earlier model. I couldn't really find another nVidia in my price range that was worth trying at this time. I did stumble upon a Radeon card that appeared to worth trying. So I placed an order and should have it arrive & installed this weekend (I just looked at the webpage today and noticed its now out-of-stock, hope that's not a bad sign).
