>The Asus cards use active cooling of the video chip, rather than the passive cooling used by Diamond, and I know from experience that the card runs hot, so in a case with questionable air circulation the V550 isn't a great choice.

>I still think the Matrox cards, in particular, the G100 and G200 AGP cards, are the best bet as far as fast, stable AGP cards with good gaming support at the moment.
Hmm, nice point
Maybe I'll try Asus, Matrox is kinda hard to get in my country now, since my country currency dropped to 400% against USD.

>This may seem like a silly question, but if you aren't having problems with VFP 5, why switch to VFP 6 right now?

Well, you did not ask a silly question, but I did a silly action (so surprised that I realize it by now), hard to beleive it myself but sometimes I'm crazy with a brand new product, but I always end up regret it myself (even though sometime new product does even better than old one)........
But I think it's too late now to change it back to VFP 5 (wasting to much time), so all I can do is just try to changed some hardware (hope this works) and wait until the next release (maybe VFP 6.1), but until then I just can say to myself, "Happy Headache".......
