This EVGA Step-Up program is a bit misleading don´t you think? I was looking that I could change my GTX 580 Classified Ultras to GTX 680s by only paying shipping. So a couple of days ago I hit to #0 in queue. Then I found out that I would need to pay about 130 (including all shipping) per card to get new cards. I am not paying that, because there isn´t so big leap between Fermi 1GHz + and GTX 680. Plus I would get lower VRAM.
I will probably wait some beefier cards.
