I'll give you 2 good examples, "lost planet" not new but very demanding of video and cpu
Yep. I actually got Lost Planet 2 free with my rig (I bought all the parts, save the monitor, through Newegg and that was a special they were running. I'm not sure which actual component triggered the free offer, or if it was just a specific dollar amount for the purchase that did it.)
Even with that rig, running Lost Planet 2's benchmarks with the highest resolution and all the bells and whistles active, I only get a B rating.
