JackBFC7 :
I currently have a motherboard suited to a amd processor. I want to upgrade it to get a intel i7. I was just wondering what else i will have to replace like my ram which is [AMD] 8GB Patriot 1600MHz DDR3 etc.
The processor and motherboard in my signature are really really good value for money, and will be compatible with your old memory and other computer parts.
BTW, you probably know this already, but just in case.... an i7 4790 is an excellent CPU, but for most applications including ALL games, an i5 4690 is very nearly the same speed for about £70 less.
i7 are about 33% faster than i5 only when doing multithreaded tasks such as heavy duty video editing or 3D rendering.
