Being in love with computing technology can be (is!) sometimes pretty expensive hobby especially if you want to be constantly up-to-date with latest harware and yes, games. It was not a long time ago when I decided that my rig needs a little bit of extra power for certain purposes such as getting best out of Crysis and some photo editing and so on. (all right, I wanted the highest hardware score in Vista:)
So I prepared a wee coffin for my old Intel Q6600 and went to look for it's replacement. What caught my eye almost instantly was glorious masterpiece from Intel with codename Q9650. When I got home one day a little box was lying in the hallway of our house and so I went to open it and so I went to install it and so on only to find out that my old motherboard wouldn't support it. Its BIOS was un-upgradeable (plus few more other reasons) and so I went out again to look for new motherboard. This time I had to have it instantly (yes the very same day) but you wouldn't believe me how very few shops in London sell motherboards. I managed to find one and only ( Asus P5Q PRO ATX iP45) and there I was on my way home with smile totally excited to set it up and get it running. Well again to my dissapointment I realised that this motherboard just won't fit in my old Dell chassis because Dell's speciality is probably custom made hardware or at least motherboards which are fitted in the chassis basically upside down + few extra weird things which are here (in my humble opinion) to prevent you from upgrading their computers with other than Dell's hardware. I was a little bit sick for a while and again I went in the same shop to get suitable chassis and yes, even new power source (1050W). Luckily this time was everything fine and now, please, let me share my (good) experience with Asus P5Q PRO ATX iP45.
