I have a system I build myself a little over a year ago. The video card I currently have is an ATI 9550. It's an AGP 256MB card. I bought a new hard drive to install Vista. I can't use a beta OS as my primary OS, so am putting it on it's own drive. Before installing, I ran the hardware compatablity check program. It said my video card would not support 2.0 pixel shading. I was able to install Vista, but I don't think I'm running the Aero software. I'm interested in purchasing a new card that is compatable with Vista. At first, I thought it would be silly to buy another 256MB card. If I'm getting a new card, I figured I may as well upgrade to a 512MB card. A friend of mine, however, told me that the amount of memory isn't everything. He said the speed of the memory on the card is also important. As such, he says some 256MB cards are actually faster than some 512MB cards. I suppose I would be willing to purchase another 256MB card if it's faster than what I have and is compatable with Vista. Can any of you recomend a video card that meets these specks? A TV tuner isn't required for my setup. One day, I may add a second monitor, so I'll probably need something that supports dual moitors. Before I talked to my buddy, I had found a 512MB card on Newegg. It's a Sapphire X1600PRO with GDDR2. I'm wondering if I can find something better.
Any and all information will be greatly appreciated.
