The markets have not treated NVIDIA all too kindly recently. Website Hexus has been keeping track of share prices from many top tech companies recently, and have noted that NVIDIA has suffered a small set back. In a 22 day period, pieces of the NVIDIA pie of have gone from $23.52 a slice to $19.76 a slice -- a loss of 16%.

Stocks go up and stocks go down, so this fall isn't by any means shocking. However, the price-plunge could be indicative of the market's appraisal of the current battle between the GTX 280/260 and AMD/ATI's 4800 series cards, which have recently gone up for sale.

At the heart of the GTX 280 is one big GPU -- and with this much silicon, it is easy to imagine that yields might be much lower than the smaller 55nm GPU sported in the 4800's. Lower yields mean higher manufacturing costs, and this translates into the GTX 280 initially selling around the $650 mark.

Neoseeker will have a full review of the HD 4850 on Wednesday.
