This thread is so excellent.
In 2006 however, esp towards the end of 2006, we should start to optimize for 1600x1200 gaming experience liao. This is because excellent 20" 1600x1200 monitors like the LG 2010P is dropping price and getting so exciting.
For this kind of res, need great GPU of course, but 256bit is getting to be important esp if you want to do this res with AA and AF - but of course everything still depend a lot on benches. If you accept this argument, power enthusiast level should start from 6800GS liao.
