- FX 8100 or FX 8320 or FX 8350?
- Haswell won't be worth the money for you if you're just gaming. Now, throw in programs that use transactional memory a lot or AVX 2, and we're talking... Those programs are rare though.
Haswell is a bleak 5-10% performance increase over Ivy Bridge. If you have the FX series, it is better for you to stay where you are at and wait for Steamroller instead of upgrading for marginal performance increases.
