I have also decided on the 6600 gt. For the 4600, I have heard many successes with only Leadtek 6600gt. I am not sure about any others.

Where did you read that the Ledteak was the only 6600GT that worked nicely with the DELL 4600?

I had the Leadteck 6600 Gt card on my Dim 4400 system, and it worked great, but decided to return it for a later new system purchase....I just made sure I had the pci slot next to the apg card empty for better cooling, un-installed the old driver, rebooted, used a driver cleaner next, than turned off the system and installed the video card.  Booted up and installed the new video card driver.  No problems at all for the time I had the card...

SR45,

 

Thanks for the info, I believe I'm going to get the 6600GT soon. Do you remember which driver cleaner you used and where you got it from.

 

Thanks again,

Rob

Here you go....Good luck

I just installed an XFX 6600GT in my Dimension 4600 two weeks ago and everything is running awesome! I too have a 250w power supply. And used a Y splitter into the CDRW.

Definitely use Driver Cleaner and run it twice after you uninstall your current drivers. Reboot into safe mode and run DC. Then reboot and install your new drivers from the CD. I'm currently running the 66.93 driver.  

I already have 66.93 loaded with my fx5200, so all I have to do is swap out the cards if and when I get it, correct? As far as the power supply, the 4600's 250W is minimum rating, and I believe max is 350w and the 6600gt is "recommended" to use a 300w supply so we all should be fine.

Just my opinion on the 250W PSU- The short version, for the long version see link below.

Had BFG 6600gt OC for 4 months. Started getting lock ups. New driver, spy bot, Antivirus, still lockups. Thermaltake 420W PSU, no more lock ups. Higher fps.

That's the same one I have.
