At the weekend we published our preview of Counter-Strike: Source, the latest game to be released by Valve. Counter-Strike: Source runs on the excellent Source engine which also powers Half-Life 2. We noted in our preview that even at high settings the engine ran well and performance was excellent however as with other new engines there is always a lot of questions around what card is faster. Luckily Valve have provided a tool in the latest build of CSS which answers that very question and we at Driverheaven have been lucky enough to have access to it.

So today we will be running ATI and Nvidia\’s high end cards through some Source benchmarks and reporting to you which card you\’ll want to invest in if your looking for the best performance from the Source engine.
