What components should I get?

[Your Computer]

All the components i listed would work fine for your budget and standard. Every other recommendation listed by the others is really unnecessary and undesirable from what you said from your posts. BTW, the Bulldozer i listed is a quad-core; i would never recommend anything greater than a quad-core until 6-cores catch up to near 6ghz. The RAM, CPU, GPU and Motherboard combination i offered is more than enough to record games at 60 FPS without any or much loss in performance (720p). With the HAF 922 case and the better CPU H&F there's room for overclocking, especially since the Bulldozer has an unlocked multiplier, which makes it easier to overclock than most Intel processors. Due to the better memory controller in the Bulldozer, you can get better RAM speeds than a Phenom II, which would increase overall performance.
