So I decided building a PC is cheaper ... a question?

So after quite a bit of time I've decided to build again rather than buy from one of the Custom PC companies. Mainly be used for for Photoshop, Lightroom and gaming, looking forward to my free copy of Metro Last Light and the coming of BF4.

System Build:
Corsair Carbide Series 300R Windowed Black
MSI Z77A-GD65 Gaming mobo
Intel Core i7-3770K (CORSAIR Hydro Series H60)
G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 SDRAM DDR3 2133 (PC3 17000)
SAMSUNG 840 Pro Series MZ-7PD256BW 2.5" 256GB SATA III
WD Black 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s (storage drive)
CORSAIR HX Series HX750
MSI N680GTX TF 2GD5/OC GeForce GTX 680
and of course a few other perennials

So the question: I'm going to install Windows 8 - :scratch: - and am curious to know if any users have StartIsBack installed? Read a lot about Start8 but seems from the reviews that StartIsBack is better implemented than Start8. Too I'm quite open for other suggestions.

I know Microsoft is releasing an update in the future that might supersede this program but my thinking is for $3.00 I can have the Windows 7 experience in the mean time.
