Upgrading components is inefficient for future proofing. Try improving your cooling solution and overclock. Add one of these to your case and your only oc bottleneck will be your power supply: https://www.amazon.ca/O2COOL-FMS0003-Sport-Carabiner-Misting
Maybe /u/Valkyrie23223 doesn't know the link but at least he/she has told me where the main problem was. I have already ordered on Amazon an intel Xeon. I couldn't find a "0.4 MHz" clock but I found this (https://www.amazon.es/anal%C3%B3gico-Digital-impermeable-estudiantes-cron%C3%B3grafo/dp/B01I14VTZQ/ref=sr_1_1) SANDASB 0.20 MHz clock which I think will be enough
Perhaps you could learn something from this and be more constructive next time
Honestly, that just sounds like you're going to hurt yourself. You'll need to get a case and some liquid cooling to prevent that. I'd recommend buying this case, filling it with water, and standing in the middle of it to prevent overheating when you plug the build in.
This and phone as monitor
I don't know my Xeons. Had to look it up. Q4'07, eh?
It'll still play many games decently but I'd vastly prefer to have a G3258 given it is 1.5x as powerful on single-core performance (for NEARLY EVERY PC GAME EVER) and takes half the power.
The I find the 750 and 750 Ti's are available at the same price point when building for yourself; always get the 750 Ti if available. Still less than 65w in operation. You could run a G3258 + GTX750 Ti off a friggin' cigarette lighter.
I can narrow it down for you, either go with an 8086 for $3.66 or an 8086 for $699.
You're forgetting your HDMI cables. Buy a couple hundred of these and you should be good to go
