The performance of the Radeon 9800SE is close to that of the Radeon 9600Pro (slighty lower than it), so the card is a good deal. I think there are drivers out there that can do the mod without flashing the BIOS, but only about 25% of the cards can do it without getting artifacts. So you'd get a good card for $150 with a chance of it being a great card.
I did not know the Radeon 9800SE came with the HL2 coucher coupon. I thought it was the Radeon 9600/9800XT and the Radeon 9600SE, but it could be that card too.
I think the whole deal with ATI and nVidia fighting over the rights to bundle HL2 with their cards as funny. At $10-15 a pop (when normal bundled software costs the card manufacturers only $5) its a big deal. The only problem is the game runs so bad on the FX cards that nVidia would have only been able to package it with the GeforceFX 5900 or faster. These cards are limited to a much smaller audiance do to their prices. ATI on the other hand could package the game with their Radeon 9600/9700/9800 cards with no trouble as HL2 runs very well on their cards. Being able to sell a card for just over $100 makes it MUCH more avaluable to the public. Valve must have realized that ATI could move about 10 times as many games this way.
