What about the I5, it will out perform the Bulldozer in pretty much all games. The Bulldozer will work but then again so will a Pentium D or Core 2 Duo but you don't see people recommending them. For gaming the I5 is all around the better CPU and can easily overclock to 4.5+ with just a good air cooler. Just look at the benchmarks.
Like I said it's not a software problem it's a hardware problem, the IPC being in efficient being one of the big problems No hot fixes or Windows 8 is going to fix all the problems with Bulldozer. The only thing that can fix it is to go back and fix the architecture.
