Hi folks, I am wanting to go from the switch of Xbox to some serious gaming. I am looking to play the likes of Battlefield, this new Zday game and other FPS types at the minute but want to also think of future gaming ventures that I might get into. I am preferably wanting to go through overclockers.co.uk or scan.co.uk as they offer credit over a fixed term which means I can keep my savings. I started of by wanting to just buy a tower system like Alienware and get going but the more that I look, the more I want to understand the computer that i will be using. I am a 34 year old mechanic and a great believer in trying new things so this is where I am. I have watched a few videos from Newegg and still dont fully understand what parts would be best for this type of system.

This is what I have thought so far,

I was thinking of the i5 as from what i understand, the i7 is not going to benefit me much with gaming and is a bit of money extra ? I have a hard version of Windows 7 professional already and have contacted microsoft who say that it is fine for me to install it on my new system. I was thinking of a budget of around £1000 all in including a good monitor but i will stretch another bit of money if it is going to GREATLY benefit me. ANY help with this would be greatly greatly greatly greatly appreciated.
