Sapphire Radeon HD 7950 (Mac Edition) • 3GB GDDR5 Memory • 800 MHz Core Clock (5000 MHz effective) • 384-bit. These 3 cards were salvaged from old Mac Pro towers we recently recycled.
Intel Core i7-6850K 3.6GHz, 6-core, 12-thread, 15MB cache • 40 PCIe lanes • Most affordable (40 lane) Intel Core i7 available – confirmed on Gigabyte’s CPU Support List.
Gigabyte GA-X99-DESIGNARE-EX (rev 1.0) • Supports (true) 3-way x16 PCIe video cards in Crossfire mode • To achieve 3-way x16, all of the following interfaces must be unpopulated: M2_32G U2_32G_2 PCIEX8 slot (5th full slot)
Populating ANY of these interfaces would have dropped the respective video card(s) sharing those lanes, down to x8.
Had to use the U.2_32G_1 interface for the Intel 750 Series NVMe SSD since the M.2_32G and the U.2_32G_2 could not be used.
An illustration of how this board gives me the (3) PCIe x16 lanes I needed is included in my pics.
Wanted x16/x16/x16 and got it! Small sacrifices were necessary, but no biggie.
Ridiculously fast! Worth every penny.
What a beauty! Awesome showpiece case.
Keeping everything running nice and cool, even OC'd to 4.3GHz. Very impressive AIO without running tubes and reservoirs everywhere.
