On the upside, the folks at Fudzilla had since been able to source a couple of pictures of the low-profile 256MB and full-size 512MB HD 3450 graphics cards from Sapphire, both of which are passively cooled making them a well suited low-cost solution for HTPCs.
Not far behind PowerColor, Sapphire has also announced a range of new graphics cards and it's the first company to announce a Radeon HD 3470 product. However, Sapphire hasn't posted any actual pictures of the cards, which is slighlty dissapointing.
Sapphire hasn't even provided specific clock speeds for the cards in question on its website, so we can only presume they're clocked at the reference speeds. The only thing we know for sure is that Sapphire will have 512MB versions of its 3450 and 3470 cards.
