Sparkle has a new lineup of entry-level GeForce 8400 GS graphics cards on offer which carry one distinct difference over other entry-level NVIDIA/ATI cards, they connect to PCI-E x1 slots rather than x16.
Being entry level cards, the bandwidth of a x1 slot is more than sufficient for general tasks. But on the other hand, with nearly all desktop motherboards sporting at least one x16 interface these days, I doubt there's much of a market for this type of card. And what's really surprising is that Sparkle have gone all out with the new x1 series, introducing no less than eight of them with varying amounts of memory and passive or active cooling solutions.
