Hi I'm looking to be buying a p.c in the next couple of weeks and am in need of some advice. I only have limited budget for a p.c and was wondering what to buy? How fast I need it etc. I'm wanting to use it mainly for online sports trading, aswell as spreadsheets and general day to day stuff. Would prefer a 18" screen and preferably an all in one pc. Though my budget would be stretched to make £300. Am I being unrealistic. I would be grateful if you could give me your views as I have no clue on this subject. Thanks.
