I've always had Darcy down as a bit of an intellectual snob, rather than a traditional snob. Not that his friend Bingley seemed particularly bright, but perhaps Bingley's kindness of heart and simplicity appealed to a more complex man.
Darcy doesn't appear to venerate wealth - he avoids a planned marriage with the wealthy Anne de Bourg, and he seems to avoid the Bingley sisters for the most part, certainly evading or seeing through Caroline's attempts to capture him. They are relatively rich, if nouveaux.
Perhaps he venerates breeding more, but it doesn't make him want to court cousin Anne, and I've always thought he disliked Lady Catherine, who is technically highly bred (though in reality she's one of the rudest, ill-bred, people in the book).
He doesn't need to marry for money so even before falling in love with Elizabeth, he could have married anyone he chose, and yet he didn't. He presumably, with his wealth and connections, could also win a highly bred wife, and yet he hasn't. He hints at high standards when Elizabeth is reading at Netherfield. He's obviously dismissive of the less intelligent - Mrs B, Mr C, Sir William Lucas; but IIRC he's respectful towards Charlotte Lucas at Rosings, who is intelligent.
I think he's looking for someone to meet him on an intellectual level, but perhaps he doesn't realise it at the start.
From character theory - an author will typically give a character a want and a need and preferably have them opposed to each other for added tension and comedy. They will be aware of the want but probably unaware of the need. What were Darcy's wants and needs?
