Manu should make very little diff for the 9700 cards, all ports and features should be the same so all that is likely to be different is the box and sw if there is any, still best to confirm it has TVout and the ports you want, I haven't heard of any manu oimitting the dual RAMDACs or using DVI-D so dual display should be standard too.

No additonal cooling is needed, you should get very close to 9700PRO perf and all you need is to flash or edit the BIOS of the gfx card. I have heard some cards can be o/c'ed without the need to flash the BIOS but I'm not sure which ones or what tweaking program you'd need. Basicly the only diff between the 9700 and 9700PRO is the clock speeds and the 9700 much like the 9500/9500PRO have a fair amount of lee-way in them. Of course the 9700PRO is going to have faster rated RAM which will o/c a little higher but even so the 9700 is quite a bargain! Here's some UK prices:
