1 big problem with the proposed parts. The 8th gen i3 8100 is not compatible with that h110 motherboard the 100 series chipsets only work with the 6th and 7th gens Intel cpus. 8th gen requires a 300 series board.
Yeah, I was going to point that out too. Part of the reason why I said perhaps a second look would be a good idea. Good show going to it right away though, just in case they didn't answer back.
And looking more closely, they actually have the same cache, which is probably why there aren't significant performance differences. I'll retract the opinion that it might hold that card back significantly, although it might, on some titles or applications that see significant performance advantages with the presence of additional cores or at least additional hyperthreads.
Even so, putting an i3, even one with four cores, in this day and age where the four cores on an i5 needed to be increased to six for obvious reasons, doesn't seem like a good pairing. I guess if ALL you are going to do is browse the internet, run basic applications and game with no overlays, recording, streaming or other heavy multitasking, then it would be ok. If you are going to do any of those types of simultaneous multi tasking, it's probably going to be a bit much for that sku.
Also, don't be surprised if you need to replace that builder series CX unit before long if you run it with that card. Clearly the capacity is high enough, but that is not one of the newer CX units, it is an older one which means it likely already has some miles on it, and those units have a clear and easily pointed to history of early failure when paired with gaming cards or when used on any system that is going to consistently be under demanding loads of any kind for sustained periods of time. They were built using a rather poor capacitor selection and we've seen them fail time and time again when used with any gaming card that pulled enough power to require supplemental six or eight pin power connections.
Use it if you wish, but expect to replace it before long. If you don't end up having to, great, you'll be one of the few. But if you do, at least it won't come as a surprise. And it shouldn't.
Is there anyplace specific you need to, or prefer to, purchase your parts from, or are any of the common vendors in Canada all good for you?
