LeRock :
I am not quite sure how to quote all of you at once. But I've read all the replies, and to start with, I am very grateful for the replies. Thanks.
So the jist of it is, the current hardware isn't particularly good, and I should probably upgrade the CPU & GPU. I was looking at a GTX 1050ti earlier as the replacement, and I'll probably go through with that.
Also one of the other topics raised on here was a proccessor, in which the I5-7500 was mentioned, that will be upgrade no.2 most likely. It looks good. I have one question though, as it is a different CPU, someone mentioned I might have to update the BIOS on the motherboard - I'm not that clever with PC's so, why would I need to update the BIOS? Does the cpu have a different coding or something?
feelinfroggy & Constantine- Thanks for the advice, I will probably follow through with what you've stated.
Brad- Depending on how much money I have, it will either be the 1060/1050ti, thanks.
Keith- Regarding RAM, I will probably just buy a set of 2x8 sticks of RAM at a later date, as you say, it might be difficult to try and find the same brand/model as what I currently have installed.
Thanks all.
Since upgrading from the i3-7100 to the i5-7500, you will not need to update the BIOS because they are processors of the same generation. I also recommend
1: GPU - this will make the biggest initial difference
2: CPU - this may or may not make a difference, depending on what games you play. Some games are more CPU intensive. If you don't play any CPU intensive games, you may only notice a couple FPS improvement going from an i3 to an i5.
3: RAM - 8GB is typically plenty. I game at 4k max settings with a 1080ti, and doubt that I use more than 8gb of RAM, I will have to double check to see an exact amount. The thing with RAM is, having more does not give you performance increases. Going from 32GB to 128GB would not make a difference at all in gaming. The issue is not having enough of it drastically kills performance. It never hurts to have extra, but why waste money if you don't need it.
