Quote - *What's the difference between GS, GTS, GTX, WXYZ

• Coudn't tell you off hand, but Nvidia has a comparison chart on it's web site, certainly as far as Vue is concerned the 512 RAM on card would be more than sufficient, I currently use the 256 version of the 8600!!
  I am thinking of upgrading the graphics card though!!

I found it : http://www.nvidia.com/object/graphics_cards_buy_now.html

this a little clearer with this
Thank you so much
