K, so I suck at computer hardware.
I am buying this bundle http://www.aria.co.uk/Systems/Bundle...roductId=44489 to improve my computer's performance during 25 man raids, but I need all the remaining parts to go with it. What do I buy? I want to be able to do 25 man raiding without any lag what so ever.
I have a budget of £600~ , but would prefer to stay below.
Buy the components individually and build it yourself this will save you more money to spend on other components. What do you have that you can re-use? OS, optical drive or even hard drives? If you have all the things listed above then you will manage with your budget no problem.
This will leave you with some of your budget for a new case if you have all the other stuff as mentioned above including monitor. Don't be put of building it yourself, check out some guides on youtube and just copy them. You save a ton of money and get alot more out of your budget than buying pre-built.
