It's because benchmarks indicate the 260x performs less well than other graphics cards. Many people view the 280 as better for gamers and the 280 for consoles—though that's a bit of an exaggeration. The gap between them is around 3 to 8 frames per second. I believe the 260x is still a solid card, but it lacks what most gamers need from one card: 1080p at 60fps or higher when running high to ultra settings. These are the baseline requirements in modern gaming for roughly the past couple of years. Your perspective might differ, but I stand by my view.
That’s what people expect, but just because the 260X doesn’t perfectly fit their requirements doesn’t mean it’s a bad card. It can handle GTA V at high settings with smooth performance, and you can adjust settings to get around 60 fps. In games like GTA, you don’t always need top frame rates constantly. I imagine it works just fine in a first-person shooter too, though graphics aren’t as critical there. It doesn’t matter if I’m on low or high settings in Battlefield 4—I usually get similar performance. If you want better graphics or higher frames, you’ll have to invest more, but if you’re okay with lower settings, you won’t pay much.
Sorry, I don't own a GTA V or an i5. The 260x is a decent card, but it's beginning to reveal its limitations. The OPs CPU and GPU are roughly balanced, leaning slightly toward the CPU with an i5 and 260x. If you're planning to switch to the K processor now and later upgrade to a strong GPU, that's perfectly fine—unless you prefer sticking with a solid mid-range setup right away. It doesn't have to match your current choice, just what they expect. The OP might notice some improvements using an i5, though. I'm not playing the game or owning hardware, but I've read enough reviews to be cautious; there are areas where the game relies more on the CPU.
There a great article on annandtech on the A10 7870k which shares the cpu cores with your 860k. I bought the A10 based on the article and figured GTA V was a game to avoid cause it really needs cpu horsepower. They also used an I5 for comparison with several graphics card and one was a 250 or 260 I forget which. The I5 blew away the A10 and others in GTA V. Its an article on the A10 7870K but allot of the gaming benchmarks are aplicable to what your asking and you might want to check it out. Also check out the Xeon 1231 v3, Its close in price to an I5 but no iGPU and twice the threads and may be the better option. With my A10 I knew that on newer games it would be 720 on newer games but your situation is diferent. Anyway I hope this helps somewhat.
