I have always used Nvidia even since the pre 2000 days of CS when people still played with their 56k connection so I am stuck with them and will never change. They have been with me all the way and they are going to keep being with me too

There are two manufacturers leading the way on graphics cards: Radeon (ATI) and Nvidia (Geforce). I've been impressed with both in the past, but for the moment I'm leaning toward Radeon, as they've pipped Nvidia to the post with their latest release: The ATI 3870 X2 card has a whopping 1024MB of onboard memory, and a super-fast graphics processor. It truly is the Ferrari of cards, but it's also a lot bigger than a lot of others. So if you opt for a different case, make sure it's going to fit in.

right now im using the 4870x2 from ati
