Good combo dude.
That card will handle pretty much anything at max settings at 1080p.
That's a great cpu for gaming and you wont see it bottleneck a 670.
Also which 670 where you looking at in particular.
is 670 a good deal when a 660 ti can be had for $100 less for just less than 10% lower performance which when oc'd would bring it on par with a stock 670.
for 1080p i suggest you get 660 ti msi power edition
That's a good card, but bare in mind if you do see another factory over clocked card with a non reference cooler going out on an awesome special do consider it, because all 670's boast fairly similar performance and I don't know of any that are particularly prone to malfunctioning.
