Looking to get the https://www.overclockers.co.uk/8pac...hz-ddr4-extreme-overclocked-pc-fs-003-8p.html But I need 3 RTX 2080Tis, not 1. Looking at the motherboard it only supports 1 GPUs. Are there any that support 3? And I guess I would need a larger case too? The reason I'm looking at this PC is that the 9900K is OC to 5.1 GHz which is what I need.
