Video Card upgrade

[Herhey]

Was thinking of upgrading my video card soon.

Then recently my system started going nuts with weird on screen mayhem when I used a certain program.
Then when I booted up my system this morning, the desktop was getting littered with weird graphical junk which quickly got horrendous, and then my screen went black (no video signal?).

When I rebooted,just going through the boot sequence the video is really screwed.
(can't really describe it).

So it's definitely hardware.
I plan on doing a test with a different monitor later, to make sure it's not the monitor that's the problem.

If it's not the monitor I will assume it's the vid card.

Which (finally) brings me to my question.

I would like to buy an 8800gt, but only have an Antec PSU Model : SP450 (450 watt).

Is this enough to properly run the card?

Some places I have read, say it's sufficient for an 8800gt.
Other places say it isn't.

I would rather not have to upgrade the power supply as well the card.
But if I have to I have to.

Any help and comments would be appreciated.
Thanks

i would start by pulling out the vid card, cleaning the contacts, and reseating it.

the 450W should be ok with an 8800GT.

Thanks for your response Midknyte.

I tried as you suggested, but that card has had it.

I have a 13 year old ATI pci card I am running right now so I can use my system.
(2 megs or ram woohoo).

Definitely have to get a new card soon.

Thanks again.
