Will This Work?

I'm currently running a graphics card that is in a PCIe 2.1 16x slot... I'm badly in need of an upgrade and the card I'm looking at runs in a PCIe 3.0 16x slot... would I be able to use the card and would there be any loss of performance

Even a 1080 ti can't saturate a PCIe 2.0 16x slot, it just doesn't matter

CPU: INTEL Core i7 4790k @ 4.7Ghz - Cooling: NZXT Kraken X61 - Mobo: Gigabyte Z97X SLI - RAM: 16GB G.Skill Ares 2400mhz - GPU: AMD Sapphire Nitro R9 Fury 4G - Case: Phanteks P350X - PSU: EVGA 750GQ - Storage: WD Black 1TB - Fans: 2x Noctua NF-P14s (Push) / 2x Corsair AF140 (Pull) / 3x Corsair AF120 (Exhaust) - Keyboard: Corsair K70 Cherry MX Red - Mouse: Razer Deathadder Chroma

Bit of an AMD fan I suppose. I don't bias my replies to anything however, I just prefer AMD and their products. Buy whatever the H*CK you want.

At this point, no, you will not lose performance. But, assuming you get a high end card, it probably will bottleneck the next GPU upgrade you do.

Yep. A PCIe 2 x16 has the bandwidth of a PCIe 3 x8. You will be 100% fine, even with a Titan Xp

Ultra is stupid. ALWAYS.

That depends on whether the PCIe slot is limited to 2.1 by the GPU itself or the board, PCIe is forwards and backwards compatible, so it won't be an issue no matter how old it is, but but 2.1 is enough for even a high end card.

Yours faithfully

Assuming you have 2nd gen intel cpu, dont go above gtx 1060 or rx 580, or you will be bottlenecked by cpu itself, otherwise pci 2.1 wont be a problem, if you are not using some pci cards like gigabit internet or some highend sound cards... (if you are using only 1 gpu you wont see any difference between pci2 and pci3)
