the last time i upgraded i went modestly all out and got an asus p9x79 pro mobo, a 3930k cpu and 64GB of quality ddr 3, ( i do content developing too. ) and, an asus 1080ti videocard. I've overclocked the DDR3 and the CPU and video card, and they're pretty fine, actually, for running Trainz. i recommend this combo for 60FPS at medium trainz settings.
thanks. yes, ddr3... i'm looking at a complete rebuild for trainz and other game-z. going 65GB ddr5 ( keeping to a safe 5600 clock ) on an asus maximus and an asus 4060 with 16gb memory, thinking i don't need the wider memory bus but do need the 16GB to keep inside the video card and not borrow system memory. CPU will probably be an i7 of some kind, maybe 13700k. does this sound reasonable? ( this isn't that expensive a buy if you don't drink and don't own a car and have no mortgage and are a single 77 year old male who doesn't do 'fine dining' : )
upping to a 144hrz LG nano pix-like monitor with G-Sync, which, i have to admit, does look better than my buick sedan grade fine monitor from several years back...
