Deciding whether you should spend 900€ or 100€ to get precisely the same performance is not a decision dictated by budget. Only a moron spends 9 times the cash to get the same performance.

The fact that AMD's 100€ offering gets you precisely the same performance as a 900€ cash-waster is the kind of stuff that makes or breaks the performance of your workstation.
After all, for the same cash some idiots waste on a i7 processor, anyone can purchase an AMD FX processir with 6 or 8 CPU cores and then spend the remaining cash on high-end GPUs.
Again, Intel fanboys usually take jabs at AMD but they seldom back them up with evidence.
