the 4670k is a good CPU. It won't bottle neck your new 760.

I know they're not like the Gigabyte beast above, but I think these cards are good for what your brother will be using them. Especially the Twiin Frozer looks great at a price cheaper than the Galaxy & PNY reference cards. I'm working on project called uthink pc to single out video card price to performance leaders and if we were getting an equivalent price for the MSI card here in the US. I think this one would lead at this price point.
