I currently have a rx 580 8gb and im about to pair it with a xeon x5650 (6 core 12 thread 2.6ghz base 3ghz turbo) that i have seen for 11 USD .I have seen a comparision video of this cpu to a i7 8th gen and the i7 outperfomed thr xeon by 20-30 fps but with a huge price difference .So is this a good combo or should i change the cpu (z600 workstation with a lga 1366 mobo and 650w psu oem)
