Generally speaking, yes the old Core 2 Quad CPUs are still viable for playing games. Games that are CPU intensive will not run as good as PCs with more modern Intel CPUs.
Core 2 Quad CPUs are definitely better than the 1st generation AMD FX-81xx Bulldozer CPUs and should be comparable to AMD's FX-83xx 2nd generation Piledriver CPUs that many gamers are still using.
I have to disagree there.
I had a Q6600@3.2 and eventhough it was (and still is) a great CPU, it was hard to play with high resolution and definition with some games. Like Verdun or PlanetSide2. Also, it would be hard to surf the net while encoding with Handbrake. Even worse when downloading stuffs on some newsgroups, the CPU would go up in smoke and I wouldn't be able to do anything till the download was done.
I changed to a FX 8370 and games are full rez and with no lags, and I can encode and do other things at the same time now. I have enjoyed my Q6600 for many years, but the FX is a real change now for me, and it didn't cost me much
