I want to mention before I start that I am aware there are perhaps more appropriate forums to post this particular question on, but I feel a stronger connection to this community and feel this is a more supportive and less judgmental one. So here it goes.
I am currently a student at university on quite a tight budget, but want to update my computer to play some of the newer games that have been and are due to be released. I enjoy tinkering with my hardware but I am in no way a master. In fact, I consider myself still to be quite naive.
Here are my current PC specifications as taken from DirectX Diagnostic Tool:
Operating System: Windows Vista Ultimate (6.0 Build 6002)
Processor: AMD Phenom II x4 955 processor (4 CPUs), ~3.2GHz - On a side note, it does have a turbo function to increase this to 3.8GHz.
Graphics Card: AMD Radeon HD 6800 Series - ~1GB I believe
HDD: 500GB (partitioned) - my oldest component at nearly 5 years old, I intend on buying another, maybe two depending.
Does anyone know of any online guides or books that I can read to advise me further and possibly teach me a little more about this or if anyone can inform me from their own experience which components to update first.
P.S. I built my computer with my uncle 5 years ago and have been steadily updating it since. My last purchases were the graphics card and a 750w PSU.
