Hi! i have optiplex 9020 with defualt motherboard (06x1tj) with 12GB 1600MHz RAM. i had i5 4670k(4 core and 4 threads) for 9 months but it was bottlenecking with my gpu which is GTX 1650 with 100% CPU usage and 50-60% GPU uasge in games. So i bought a new processor Xeon E3 1246 v3(4 core and 8 threads). But it shows 4 Cores and 4 threads on my PC (actually 1246 v3 has 8 threads) but it gives me 4 threads. i dont know why is it because of motherboard (06x1tj)? and still i have 100% CPU usage and 50-60% GPU Usage in my games. But on a website it shows that you should have 0.57% bottleneck with xeon processor. please suggest me what should i do. should i change my motherboard to MSI?
