I haven't bought a new one in 20 years.

Mineral oil is thermally conductive but not electrically conductive.

RAM generally does more for performance, for sure. How much did you get? I like to max out RAM when I can. Tho it'll be a while before Fireball gets maxed (can do 192GB; presently 64GB). Also, can't claim I really have a good reason for that much. 32GB can get squeezy with current browsers, but I don't do anything needing more than 64GB. Well, yet! > KM> cards that score 11,000.

Yeah, when I find myself with a higher-resolution monitor that it can't handle, then I'll consider a higher-end video card. > Well, I think some of the TVs here can handle 4K; monitors don't.

I'm fine with integrated graphics so long as it's some reasonable amount. (Unlike the Dell quadcore that only allows 8MB, that's MB, as shared video RAM. Uh, no.) > answer the question, whatever graphics provided by the i5-12600K via > the HDMI and DisplayPort. Might have to get a DP-to-DVI adapter for the > second monitor. Not sure what I have in the adapters box.

I can attest that at least with the very small fans, a locked motor can make a whole lot of heat, way more than the CPU it's supposed to cool. þ RNET 2.10U: ILink: Techware BBS þ Hollywood, Ca þ www.techware2k.com --- QScan/PCB v1.20a / 01-0462 * Origin: ILink: CFBBS | cfbbs.no-ip.com | 856-933-7096 (454:1/1) .
