I just checked newegg's EVGA cards they have right now.
The lowes price GS they sell is $180 and the highest is $210
The lowest price GT they sell is $202 and the highest is $235
Its not about how rare it is. Its about the diffrence in price and its not much. I dono what your lookin at but the prices are right there at newegg. I'm looking at EVGA's stuff since its a popular manufacture.
lowest 7600GT I see is $120 and the highest is $140.
I dono how to do a linky but try this.
Also, these are prices for new cards, it isn't fair to count that $202 re-certified eVGA 7900GT as there is no equivalent for the 7900GS, also that recertified card has been out of stock for AGES, and when it does come back, it will only be there for a day or so because they always have very low quantities of those re-cert cards.
