Hi

I am thinking of updating my video card. Am not sure if physical dimension of card or my system is suitable for such an upgrade. Will upgrade to vista when SP1 is released. All drivers/bios are current.

My computer is used for flight simulation (MFSX) and general computer usage.

Leadtek suggest 450watt power supply minimum requirement for their 8800gtx 768mg card. My research reveals conflicting/confusing opinions.

Specifications for my Antec power supply are:
OUTPUT
Max. Load

+5V +12V1 +12V2 +3.3V -12V +5Vsb
35A 17A 19A 32A 0.3A 2.0A

* +5V, +12V1, 12V2 and +3.3V maxload: 480Watts
* +5V and +3.3V combined output: 180Watts

Any any advice/assistance from users of 8800gtx cards would be appreciated.

I am going to say you need more , i use the 8800GTS 640mb and I have a 550watt Ultra Xconnect 2 SLI ready power supply no problems ...but for the GTX I say you need at least what I have if not more.

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

Notifications don't work, I only found your response by coming back to hunt up some threads, if you want, give me your email address so we can keep in touch easier!

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
