So my video card may be on its death bed (currently troubleshooting the issue here: http://www.neogaf.com/forum/showthread.php?p=127168496#post127168496)
I've been out of the loop for a while now ever since I got my GTX 580 a few years ago, and since it appears as if I may need to buy another one rather imminently, I was wondering what would make the most sense to replace it for something equal or better in the current nvidia line of products.
How does the GTX 760 compare?
A GTX 760 is only a small step up from a 580.

If you're basically fine with your current performance, then it's a good choice. Faster, uses less power, and more VRAM. But if you want a real upgrade, as you can see you'd need a 770.
