I go to 1up or friends a lot of the time.
1up has recently gone to a letter grade which I think is much better than the 10 point scale, which has gotten a bit inflated (very average games getting 7/8's when they should have 5's etc). So far the letter score seems right on the money.
I couple this with their excellent podcasts, 1up Yours and the 1up show (one a weekly audio podcast and the other (1upShow) a weekly video podcast, running about 2 hours and 40 minutes respectively). Can't beat these in my opinion, high production values and good topics/guests/diverse opinions.
I encourage anyone who games to check them out.
I also got to metacritic for an overall view on a game if I am on the fence about a purchase.
