New computer, kthnx

Alright, i'm looking for a computer, nothing special. Basically able to play CS:S without lagging (yes, the most intensive thing i'd probably do with it)

http://www.newegg.com/Product/Product.aspx?Item=N82E16883108122

is that a good buy? Will it do what i need, and do it well?

good price?
