Will Gigabyte GA-7DXE Motherboard accept Leadtek A6600GT TDH AGPx8?

Dear All,
I intended to upgrade my video card from a FX5200 to a Leadtek Winfast
A6600GT TDH" 128mb AGP8X.
The problem is my GIGABYTE motherboard is very old (Gigabyte GA-7DXE)
and it can
only support up to AGP4X. (1.5v)
Therefore when I went to the shop to buy it, the salesperson advised
me to email to Leadtek to verify to make sure that the said card is
AGP4X compatible (at least voltage-wise, i.e it can autodetect the
mainboard AGP 2.0 type and switch to 1.5 v rather than the AGP 3.0
design voltage of 0.8v)
The box, nor manual of the card, does not mention anything about AGP4X.
I have sent an email to Leadtek but while waiting for the official
reply which might understandably take very long time, I would like to
have your help:
If you have a Gigabyte GA-7DXE motherboard and a said Leadtek A6600GT
TDH AGPx8
video card and they all work successfully without any problem or
performance penalty.
Please confirm for me.
Then I will go out and buy the card straight away as it is only a
limited offer in the store and will run out fast.
(I also have a noname 400W PSU, hopefully the card can run on that as
well).


Thanks for your help.

Regards,
Luna.
