9600 pro's are pretty nice BUT.
I dunno.
I'd probably take my chances and opt out for a 9500 non pro. You can get them for like 130 shipped now, and if you email some sellers on pricewatch that carry it (I know buyxtremegear carries the 'special' ones), then you, my friend, have a very good chance at having yourself a 9700 for the price of a 9500.
What you'll want to ask is for the '9500 non pros with the 'L' memory configuration. It doesn't matter what color the board is...can be black/red/green...whatever...you just want the 'L' memory configuration, as opposed to the 'straight inline' memory configuration. If you look at pics you'll see what I mean. (memory are the little 4 black chips found to the right of the chipset/fan. People have been having good fortune with buyxtremegear . A 9700 non pro will kick a 9600's ass or 9500's ass to shreds, due to it's 8 pipelines and 256 bit structure.
Look here for details of the simple software procedure to change the card and what to look for

9600's cannot be modded, no matter what. Worst comes to worse, even if you do get a 9500 with straight line memory, you can still mod it to a 9500 pro (like me) and those give some pretty damn impressive numbers as well.
You really can't lose if you go with either cards though.
Good luck.
