I'm thinking of building a new computer (again) and I'm waiting till christmas to purchase the parts. Anyone know how the trend goes with when ATI/Nvidia release their video cards? I would hate to purchase their top of the line card and then a week later a new one comes out. I find it's really hard to find out when new cards are due out, it's not like there is a site listing the forecasted dates.

I know that crysis is the next big game coming out, so I wanted to know if anyone thinks that might pursuade the two companies to wait until after that's released to come out with new graphix cards.

thanx
