I am looking to finally switch from console to pc gaming. I have been wanting to build my own, but not being able to find ram that isn’t less than $400, I’ve decided to look at prebuilts, and found this one. Sorry I’m new to this, so the specs are on the top of the listing. I just want to know if this is a good pc. The only real multiplayer game I play is rainbow six siege, and the rest would just be story games that I would want to mod. Would this hold up with good graphics? Also would I be able to in the far feature be able to upgrade it when it gets outdated? I’m new to this, so if it would be too much or better options, suggestions would help.
