Okay, simple question. How much different is performance of a video card based on the same GPU but with different memory between a GDDR2 vs. GDDR3? Does the cost justify the performance increase? Trying to decide which to get. Thanks...

GDDR3 will be faster due to its ability to clock at higher frequencies..

what two cards are you trying to make a decision from?

I am looking at these cards: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010380048+106791921+1067928607&name=GeForce+8600GT

oh man, have you considered a HD3870 or 3850? they seem to be very low priced and offer better performance than those cards on newegg.

the 8600 is really limited, you already have a 7950 gx2? that would probably outperform the 8600 :)

Yup. You would be downgrading if you went from your current video card to a 8600.

Performance-wise, but you'd gain image quality.

but you'd still take a substantial performance hit.

true, i actually have to play tomb raider anniversary @ 1024x768 for no choppiness on my 8800 GT superclocked b/c I use riva tuner to disable dxt formats. I also turn shadows off, but i play with 16xq + trss + 16x HQ af.

About GDDR2 vs 3, I was always lead to believe that GDDR2 ran really hot, and was more prone to failure.

Actually, the new card will be for my other PC (which is using a Matrox Millenium II 8MB PCI now).

oh yeah, then go for the 8600 with GDDR3, it would be a big step up :lol:

One more questions, other than better texturing, anything I should consider whether it's a 256MB or 512MB? In other words, is the 512MB also faster than the 256MB? Thanks again...

its an 8600 GT, I doubt you'd get very good performance out of it even if it was 512, I'd say get the 256 to save money but if you are going to be playing some newer games I guess it wouldn't hurt to get the 512 model.
