Cheap second graphics card advice please

Thanks... I don't really need anything decent as I will be running my two monitors off my 4870.... I just need another video out to combine with my sound card... that will only be connected to my Amp... no monitor.

If I went with something like a Radeon 7000 or 9250 would that work on a Windows 7 machine?
I have the latest ATI drivers, but not sure if they would work with a card like that. I looked at a low range ATI HD card (which would definitely be compatible with my drivers) but I dont have a second AGP port so thats why it needs to be PCI.

Thanks

How much do you want to spend?

As little as possible mate... something off ebay! I just need a video signal that wont be displayed!
Need to be DVI though.

I recently stuck the AGP version of one of these in one of my spare computers:

Newegg.com - SAPPHIRE 100262PCIL Radeon HD 2400PRO 512MB 64-bit DDR2 PCI HDCP Ready Video Card

Then eBay might be your best bet.

If you have a decent computer repair shop nearby it might not hurt to go down and ask them what they have laying around cheap and/or used. When I worked in that field we would sometimes just give people stuff that was well off the cutting edge. There was usually a pile of parts from obsolete or abandoned rigs we couldn't use and it saved us the trouble of dusting them off in the $5 bin.

Guys there is mass confusion going on here!

OP said "My AGP slot is taken by the 4870"
(Don't you mean 4670?? They never went any higher for AGP slots )

So OP has an AGP card! 99% do NOT support sound thru hdmi for starters!
Only one I know of is Artic something or other uber expensive AGP card.

I have an AGP 4670 (DVi-Hdmi converter) HDMi cable running thru to a 7.1 Yamaha amp with pass-thru to a Samsung T260 Computer Monitor. Vision ONLY 1080P 60hz!

Sound goes thru a digi/optical cable from motherboard to input on surround Amp. (You could also use SPdif digi connection Motherboard > AMP for sound)

The EDID is NOT seen by Win 7 either!
You have to permanently set the monitor model/hz in >Screen Resolution>Display>Advanced settings>monitor> (look for your digital display driver.load)!
It will give you an option to fix @ 60hz 1080P if supported by your monitor.
