Will this be good for gaming , anything i could change for something better?
Save yourself 10 euros by not getting a CD burner, unless you're going to be burning CDs. You can get a usb boot drive
Don't bother with a 4670k if you're using a b85 motherboard. B85 doesn't support overclocking, if you can save money by doing so, switch to a 4670. Besides that I'd definitely change the gpu to a 280 or possibly a 280x if it fits into your budget.
