I would highly recommend a very good closed water loop cooling system like a Corsair H110/105, Cooler Master Nepton 280L or something similar, especially if you plan on doing any overclocking or 24/7 type operation. **Q: does it have a graphics function built in?** A: The i7-5820K does not come with built-in graphics, nor do any of the Haswell-E parts. **Q: Does it come with heat sink and thermal paste?** A: No this cpu did not come with a heat sink. Any socket LGA2011 heat sink will work, but get a decent heat sink to keep temperatures in check. **Q: can this handle 2 GTX980 graphics cards ?** A: Yes. It could handle two of them. However you are limited to 28 pcie lanes. So they wouldn't both run at full 16x speed and keep in mind that not all motherboards have more than "one" 16x speed pcie slots. For instance, even on a board with 2 - 3 pcie slots rated at 16x, you are only going to run 16x full speed on the first card and maybe 8x on the second card. If the slot is rated at 8x the second card will only run at 8x. ## Frequently Bought Together - Intel Core i7-5820K Desktop Processor (6-Cores, 3.3GHz, 15MB Cache, Hyper-Threading Technology) - Corsair TM30 Performance Thermal Paste | Ultra-Low Thermal Impedance CPU/GPU | 3 Grams|w/applicator, silver for Desktop - SAMSUNG 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
