Cheap Directx 10 Video Cards

I am in need of a decent directx 10 graphics card, with an aftermarket(3rd party) cooler. I want to stick to nvidia because my currently x1800xl was getting too hot out of the box and I was compelled to buy a Artic Cooling solution.

Try to keep the budget within 100-250 $(Usa dollar).

Any input?

why a cheap DX10 card? they cant actually play DX10 games....rickykemp

Theres not even much reason to use DX10 to begin with.. For the most part Vista has a negative performance hit over Xp, for alot of times where images are not that much better.. I am still waiting for this claimed "60% performance increase over DX9".. Because as it stand most people are having trouble matching XP performance using Vista :?

Yea.. I didn't fully understand this.

I have a pci express x16 slot.

The ati Hd 3870 is pci express 2.0

Now, I wikied it and found out that 2.0 works on the older versions.

Is this true?

And also if I use it on the older version will it made a performance difference?
