I'm looking at a custom PC build, and wanted to get a few opinions before dropping up to about $4,000. I've been saving up, so I'm willing to spend for performance, but I want to make sure I pick the right upgrades. All I'm interested in is gaming.
First off I would go for 4GB cards over 2GB. Second, unless you are running triple monitors at 1440 res I really don't see a point to getting dual cards. If I were you I would just go with a Gigabyte 770 wind force 4gb card. It will give you tons of power and it's at a decent price.
Now if you are doing graphics rendering and other professional tasks like that go with the 780 since it is 8% faster that will factor down your rendering time by a decent amount.
