First build advice needed

[BlueSpartan]

hello all (And thanks to all those that have helped me already)

Ok so all my new parts for my new build are coming but here is where I need some final help, the old parts I will be using are:
Wifi Card, 1 tb Hdd, Oc'z 650w psu, Cd/dvd drive and gtx 560 ti gpu.

So should I be thinking of replacing any of these parts before I begin my new build, I will also be using Windows 8 instead of the current windows 7 I am using.

Any help would be great

It's the 1gb version. Handles games ok on my 23 inch monitor

What was it about windows 8 you did not like.

Have you already bought Win8?

Yes
