[QUOTE="Tech Geek, post: 62483, member: 18181"] I know you read my post on this subject... but I guess it has a way to go yet. The X300 is similar to the 3D speed of my ATi 200 onboard video and it doesn't have the bandwidth for HDTV. X700 or X1300 cards should handle the bandwidth for HDTV if used with a sufficient clock speed. The fan is variable speed on many of these cards and the question is how loud is it when used with HDTV content. If the fan doesn't want to run at idle you'll want to use a tool to turn it on for some cards as some people have had heat issues without it running. FWIW I've seen X1600 cards for $69 US or $59.99 US after rebate which is about the same as an X1300. The X700 cards I've found are as expensive as X1300 and X1600 cards and the X1000 series has Avivo which is a big improvement. No point in not going with an X1000 series card. The low profile card height could be the real challenge. It's also why I went with a large case. Check the specs for the cheap half height X1300 cards because it can support a 64bit RAM interface which WILL NOT SUPPORT 10GB/sec bandwidth for HDTV. All the low profile X1300 cards I found were listed as 64bit on Newegg.com but their info has been wrong before. Not sure about X700 cards because I couldn't find half heights from the places I normally order. I think they are being dropped because of the price of the X1000 series. As for the PowerColor cards you linked... the 266Mhz RAM clock speed is NOT fast enough for HDTV even if it has 128bit RAM. Overclocking MAY work but you'd be in the same position I'm in. I won't know until I test it and I'm waiting for the ATi 650 based HDTV tuners before I make another attempt. I think the magic MHz for 10GB/sec was 315 or 325 but I'd have to do the math again to be sure. You'll be happy to know that the difference between the high speed and low speed X1300 cards is just the RAM and I have overclocked mine up to 550 for the GPU and 418 for the RAM. That speed should be way more than fast enough and I'll probably use less for reliability. Factory was 450 GPU and 250 RAM. But mine is a Sapphire and it may use different RAM so YMMV. You'd want ATiTool .25 beta 14 for overclocking an X1000 series card. [/QUOTE]
