What, you want both of'em ??
My friend had the same dilemma but BEFORE buying anything...
If you decide to buy it it would be great if you could compare them head to head.
anyway, it now seems that 9700pro is by far a better choice, no?
only reason to think about 5800 is if DOOM3 games will really get that much of a boost over ATI like the OLD benchies (lol benchies)
