New Build, what next

[Ziddon]

Hopefully getting me new rig this week.
Giving myself a jump to get back into it (gaming, photoshop, 3d, hd video editing)
Im totaly used to PCs but have been less and less last 6 yrs.

Wondering what would be the first things you would do with it, if you either had it built for you or did yourself?

1. Win8 Set up users (one neutral, one passport/gamertag)?
2. Antivirus install?
3. Test performance? (3dmark, ssd?, soundcard?)
4. Install games
5. Install productivity programs

Anything else? Any epic workflows for keeping security high/going anon?

Set Windows up, install you AV, then get your drivers / BIOS checked.

Motherboard BIOS update
Chipset drivers
NIC drivers
Graphics drivers
Soundcard drivers
Peripheral drivers

Ah good point on the drivers.
As the rig is being made for me, been told drivers should be all checked and upto date (they are stress testing the rig atm)

But if i was to look at them, im guessing just need to check the driver dates to see if up to date?

Anything other than AV and some benchmarking?
Was thinking 3d mark then something for the SSD, although think Samsung might provide their own.
