I also heard that too Jopo!! At first I heard an extra 32 but that seems like too much and now I heard 18! My upgrade will still be slow I won't be putting t4s in them! I started t5s and I'm going to stick to it
What t5's are you gonna buy if you want an 800/600 build? I can't find a good guide with t5 builds since the other one is incomplete.
