Compare this to how most PCI-E X800/X850 XT/PE's are right around $200 USD... it makes sense to consider for a few bucks more get a more powerful card with SM3.0/FP16 blends for hdr. PLUS the X1800's can do HDR + AA as well.
I have the Asus Radeon X800XT PE. It's a good card that performs well. Unfortunately, after about one year the fan failed. Although it's under warranty, I bought an aftermarket replacement heatsink/fan. I haven't reinstalled the card because I've since upgraded to an Asus Radeon X1900XTX.
