eventually, and then the 10 series will do the same to the 9 series, rinse and repeat. basically as long as its one of the fastest cards the gts will be expensive, when it becomes obsolete (relatively) its price will drop.
from the question i assume you are looking to upgrade, if you want to only spend $100 then i'd say your best bet is an OCed 7600 GT, lotsa bang for your buck, i can run FEAR with pretty high settings with just one of them.
but really, what are you looking for?
Well I have a month or two until I have all the money but I am going to build a gaming computer for the first time so I was wondering if I could get an 8800 for the same price as an 8600 by that time. but as far as what I want I would like it to be able to run dx10 or else I would go with the 7600gt. But seeing as how I have to wait for the money I was just wondering about what my options would by that time. Oh and I have been thinking about this one http://www.newegg.com/Product/Product.aspx?Item=N82E16814150229 or some other 8600 but I should probably wait until I have the money to choose. Or should I just keep looking at everything?
