You'll be fine for playing your game.

The quad core physically has two dual core processors inside of it. The increase in cache is not the difference between a dual core and a quad core. Yes it has double the cache, but that's because it has double the cores.

If you've already bought it I wouldn't worry about it.

I think you went a bit overboard for Lineage 2 there mate.

Going with a dual core instead of a quad should be alright as the prices allow for a nice budget gamer. However, you can never go wrong with a quad core (as far as i can tell), they should be pretty nice in the future.

As far as the Q6700 is concerned... i would strongly suggest the Q6600. Most people will tell you that paying almost twice the price for the same processor but with an extra .26ghz is not worth it. Besides, if you can't reach 3.0ghz with a Q6600 you would be very unlucky.

I'm not sure if waiting for the full Penryn line to come out in January is worth it either. From what I have read, they don't plan to drop the price of todays CPUs with the release of Penryn.

...Buy a Q6600; it will make you very happy!!
