Core Limits have a review up of Counter-Strike: Source, which is a great read IMO and is very detailed and nice, exploring the full potential of CS: Source and every minor detail as well with useful info and more, rating it an awesome 96%. Here's a slice:

"Counter-Strike: Source has drop-dead gorgeous graphics. With some of the latest technology implemented, Counter-Strike: Source gives the eye something to stare at. Be careful though, I have found myself many a time playing with the physics and looking at the graphics, only to have an opposing force sneak up behind me and take me out. I suggest starting your own private server to play in and investigate."

For the rest of the details and goodies be sure to head over to Core Limits and give the full review a read.
