So after reading all your advice, cheers guys, it would seem that a new rig is circa £500...
For that kind of money I think i'd rather throw more money at upgrading my rig and manning up and planning ahead when it comes to any LAN sessions in the future In fact it might serve to help towards a build for my friend who's on a tight budget.
This is however still a very interesting topic, by looking at my spec would you say the motherboard choice is adequate? I'm not too clued up on mobos so any advice you have is appreciated.
PS: Apologies for the really small squint inducing screenshot, looked perfectly legible when I editted the size!
