Hi-
Here's a 5200 mod for earlier 4x AGP machines:

Used (and good) Radeon 9800 Pro cards are getting hard to come by.
I pay up to $50 plus shipping to get a card, with 1 in 4 being worthless... add $15 in eBay and PayPal costs for a $100 sale, and there isn't much left, especially if I include shipping in the sale (which I do).
XT's demand even higher prices..... but $180+ is ridiculous......
Geforce 6800 GT cards are a real good performance card for QS machines, but they require a PC to flash them, and a good used card will go for as high as $80.
A good buy there is anything less than $140.
Too many guys are in it for the money, looking for 100% profit (or more). It doesn't help that there were so few retail options, or that they were discontinued relatively early.
Still, with the costs (and risks) associated with used PC cards, it is hard to keep prices down.
And, supply and demand rule.....
I, personally, look for about $20 for my efforts, and call that good enough.
As for the "new" cards, I think these are mostly blatant bootleg copies of original Radeon cards. Quality is a concern, as is warranty.
The "new" X800 XT cards are worthless, and I haven't found the source of the 9800 Pro cards.
The new FireGL X3 cards are also a curiosity, but they flash.
$300+ is outrageous, though........
