Default video cards

I am trying to put a system and can't decide which video card gives me more bang for my buck. They both cost about the same:
Geforce 6600 128 MB
Radeon 9600 Pro 256 MB

Please Advise

I would go for the 6600 since Nvidia has better linux drivers. I think the 6600 runs better too.

Get the GT version if you can though. It's a lot better.

That's actually what I'm putting in my system. It's not much, but I want to wait until the 8xxx series to upgrade.

Yeah I would also go with 6600GT, a difference is the mem and core clocks are aboout double in the 6600GT (500/1000) than the 6600 (300/500)

yea, go with a 6600gt, or a x800gt/x800gto they have 256 memory compared to 128, Up to you.
My current specs:
i7 920
Biostar TPower x58
3x2GB g.skill
XFI GTX260 Black Edition
640 WD Caviar Black
Vista Home Premium x64

The GeForce 6600 GT has 128MB of GDDR3 on a 128-bit memory bus, which runs at 1GHz providing 16GB/sec of bandwidth. To combat this, ATI is making the standard memory width 256-bits wide. ATI will give you the option to have either 128MB or 256MB of GDDR3 on the card. At the 980MHz frequency that is standard with the 256MB version, this gives the ATI Radeon X800 GT a whopping 31.3GB/second of memory bandwidth, which is almost double that of the GeForce 6600 GT.

This is what we meant by a configuration that seems somewhat imbalanced. You have a 256MB framebuffer with a whole lot of memory bandwidth available, but only around 3.8 GigaTexels a second of fill rate available to it. Therefore, it begs the question as to whether or not this is overkill for the shader and fill rate performance the video card provides.
The X800GTs have higher bandwidth, but the throughput is roughly the same. In fact, I did the math once when I was shopping for video cards, and I think the 6600GT actually has a higher fill rate. I think it was over 4 GigaTexels, but don't quote me on that.
