|Sorry for the late reply, i didn't have Internet this weekend...|
I know you didn't talk about the 486 upgrade, but you mentioned the 4th and 5th comment from your link:
"The reason I'm in the IT field right now is that I researched one of those 486 to Pentium adapters and found they weren't worth a s---, and started building PCs as a result. A performance hit of 5-10% wouldn't surprise me in the slightest. - by Just buy a new mobo!"
And i mentioned the last comment:
"I'm always skeptical of hardware upgrades based on old tech, but this one works fine. Moved from a 1.8Ghz to a 2.8Ghz system, on a D850GB motherboard with 1GB RDRAM... Only been a few days now, but it seems okay. For general use, speed cannot be noticed all that much. But video encodes at least 25-35% faster now. Audio encodes are much faster too, almost twice the speed as before. Well worth it... The Intel D850GB is a very solid system... Max CPU speed is 2.8Ghz at 400FSB... Must be 400FSB, not 533 or 800 or whatever else."
I just asked for help searching for some kind of compatible CPU list, because i read elsewhere it supports 533 FSB. If it does, i might find a cheaper used cpu and avoid a bigger upgrade.
I don't need a top end machine, just a better CPU, because MAME relies on CPU power and not on graphics card power. Heck, if i used a S3 Trio, MAME would run at the same speed ;) but i have to use a special 15khz AGP card because it connects directly to a 17 inch arcade screen.
I only do what the voices in my head command...
