"Answers to some of the questions"4.5 starson by ttam951
Pros: Good proformance, Good quility tv tuner
Cons: Vista Media Center, ati 550 theater
Summary: About a year I purchased this for about $200 at that time it was a very good deal with good performance equal to nv7800gtx and atiX1900gt and a tv tuner. To answer some of the questions this card has been discontinued by ATI because the tv tuner longer works with Vista's Windows Media Center. How ever this is not ATI's fault this was caused by Vista's new handling of services and programs (still works with XP). ATi tried to work around this but was unsuccessful. The gpu still works normally in vista but no more tv tuner support with vista's windows media center. However if you bought this and vista you can use a third party tv tuner software, like Snaptream's BeyondTV 4.6. This plus new ati driver, say 7.8 and up will give you full tv tuner functionality. If you some how find this for sell and want to buy in I would recommend buy it if you have XP for under $150 or if you have vista and you want a new graphics card and tv tuner and you are will to spend a little bit more money right now the best deal would be and nv880gt graphics card with a sapphire 650 pro tv tuner, both can be found on newegg.com for around $300 total.
If you still want to go with the AIWX1900 I would recommend a 450 watt min power supply and make shore you have a PCI-E X16 this is not compatible with PCI, PCI-E X1 or AGP X4/X8.
