You will not find the FX5900XT for anywhere near an R9600PRO except somewhere where they don't drop their prices over time. If you search for deals, the R9600PRO should be $40-50 cheaper than the FX5900XT.
The FX5900XT is abetter choice for the long haul, but don't forget the R9800/pro showing up in that category now too for the premium you would be willing topay for the FX5900XT over an R9600PRO/XT. The question is exactly how muchh money do you have to spend?
A Sapphire R9600Pro can be had for <A HREF="http://www.newegg.com/app/ViewProduct.asp?catalog=48&DEPA=1&submit=property&mfrcode=0&propertycodevalue=4808" target="_new">$126 US on NewEgg</A>, but the FX5900XT/SE/LX/EPL/etc is going for <A HREF="http://www.newegg.com/app/ViewProduct.asp?catalog=48&DEPA=1&submit=property&mfrcode=0&propertycodevalue=5199" target="_new">$175US on NewEgg</A>, which equates to a $49 dollar difference. I would say that's very far from roughly the same price.
I HATE POwercolor, but you can get and R9800 for <A HREF="http://" target="_new">$170 at NewEgg</A>, and that's DEVIFINITELY a BETTER Choice than the FX. And if he's willing to pay a premium, then that's the card to get, despite it being PC OEM (as if AOPEN's much better with unspecified parts). And a retail PowerColor R9700Pro for <A HREF="http://www.newegg.com/app/ViewProduct.asp?catalog=48&DEPA=1&submit=property&mfrcode=0&propertycodevalue=3048" target="_new">$179 on NewEgg</A> will wipe the floor with the FX5900XT in everything but Quake3. And a new Sapphire R9800PRO for <A HREF="http://www.newegg.com/app/ViewProduct.asp?catalog=48&DEPA=1&submit=property&mfrcode=0&propertycodevalue=4632" target="_new">$206OEM aor $215 Retail at NewEgg</A> is definitely worth the premium if you're willing to pay $49 dollars more for an FX5900XT.
I don't think the FX5900XT is as much a bargain as it one was. Other prices have fallen too.
And your statement about it with the R9600Pro may be accurate, but it does have trouble against the R9600XT, and doesn't win in ANY test. Heck I bet the FX5900XT loses in some tests to the R9600PRo.
Look at Digit-Life's TombRaider Benchmarks even at 16x12 (FX is worse still at lower res.), the FX5900 series loses to the R9600Pro, despite that memory advanatge;

Same for Half-Life Beta;

Look at anything with advanaced pixel shaders and you see it lose, only once you DO use ONLY the raw memory bandwidth does the FX win all tests, and if you're runniing things with that detail, you should be running one of the ATI cards I listed that would actually get better/playable framerates at those settings.
To get a better feel of how close the two cards are look at [H]'smost recent review of the XT, and see how it doesn't offer much more than the R9600XT, at what is now usually a considerable price.

The FX5900XT had it's time, but now everything has dropped in price and the picture changes yet again.
