Ico, I have also suggested OP an Intel i3 3220 based configuration and told him that there is no AMD CPU at that price range that can counter it, expect A8-5800K. But since I have hands on experience on both Piledriver and Bulldozer with all the Win 7 BD patches installed and some custom tweaks, I found that BD's performance can be increased significantly using some small tweaks. If OP don't want any hassle, even the simplest one, then i3 3220 is the best solution for him.
In all the reviews, tests are done by disabling all the CPU enhancing features like AMD Turbo as well as Turbo based overclocking, by increasing the Turbo Clcok Multiplier value. Also there is another feature called Core Parking, which when turned off, increases BD's performance. As I mentioned in my previous post, if you overclock using increased Turbo Frequency in high performance power mode with Core parking off, the performance of all the BD processors increase around 5% to 10% in different scenarios. There is a very simple Windows Application available for Switching Core Parking on/off on the fly without restarting. Also there is a new option in almost all the EFI BIOS versions, called HPC or High performance Computing, which when enabled can eliminate the CPU throttling at lower than the stock speed.
After applying all those, I found out that performance of my FX-8150 was increased a lot in Benchmark suits like AIDA64, Cinebench and Wprime. In AIDA64, sometimes it was ahead of i7 2600K with no CPU overclock and Turbo Clock set to 4.2GHz. I have done all those tests with my stock AMD cooler and the temperature was not more than 70 degree.
