Parts Preferences: Not to bothered as long as they all combine together and work.
Overclocking: Maybe, i vaguely understand this but im not to sure if its a good or bad idea
SLI or Crossfire: Maybe, again as above my understanding on this is a bit vague
Your Monitor Resolution: upgtrading would probaly go for 1920x1080, with a size of 23-24 inch.
Additional Comments: I've never built a PC before so this is my first build. As stated my primary function would be for games like: Battlefield, Skyrim, Fifa, etc. Since this is my first Desktop PC, I will also need all the basic peripherals.
And Most Importantly, Why Are You Upgrading: Never had a desktop before, but always wanted one, building a PC would also help broaden my knowledge of PCs helping with my Uni degree.
