Go for the Pro Evo , for the extra money (£28 i think @ Amazon) you get an extra 8gb and a faster SSD.
if you arent using the pc for CAD/Photoshop stuff which will use hyper threading save yourself £80 on the CPU and buy the i5 4670k there's minimal performance difference. read this review. http://www.techpowerup.com/reviews/Intel/Core_i5_4670K_and_i7_4770K_Comparison/
Today i ordered a similar build to you , which Sapphire 280x model is it ? the toxic is the best. the PSU will be able to handle two of those for crossfire if you wanted to go down that route? (not too sure on the brand though)
also you'll have to be running some HUGE programmes if your wanting to use 16gb, i'd go for 8. but if you have the cash why not.
hope this helps? here's my Gaming PC build. http://www.tomshardware.co.uk/answers/id-1851843/rig-bought-today.html
Well, I will edit so I will need 16gb ram and hyper threading. I'am not buying toxic edition since it's alot more expensive then others. How much more performance do i get if I buy the toxic model?
In that case my friend, the i7 is the correct CPU for you & the Ram.
Which Sapphire 280x did you order? (model number) the entry level (Dual-X) is 870mhz core and 6000 GDDR whereas the toxic is 1100mhz core and 6400 GDDR. + you get 3 free games with AMD's promotion so the cost difference of £40 is massively worth it.
Hope this helps.
