Re: First build setup! any help appreciated!
Key difference is if you intend to overclock it.
I'll start at the basics in case you don't know, ignore this bit if you do.
CPUs have a clock speed and multiplier, the k comes with an unlocked multiplier, so you can raise that and also raise the clock speed to overclock, the 2500 multiplier is locked.
Meaning the 2500k can be overclocked to higher speeds.
I actually see nw that you picked a lower end i3, so stretching the budget too far could be a slight issue, but the i5s are generally just, literally, quicker. You pretty much get what you pay for as you go up a range.
When I said HDD bottlenecking, I'm referring to the speed of it.
Ever had a brand new PC, top of the range components and it still locks up? Generally the HDD is to blame. BUT, components can always be added/upgraded laer, but since you have to swap CPUs, as opposed to being able to add new HDDs, its better to initially spend your money on a decent CPU, if you see my logic.
