I'm thinking about getting a power supply of around 500-600 Watts. I also probably need another fan to cool it. My problem is I have no idea what cards work in my computer. I'm looking for gaming cards by the way.
Well I WANT to spend nothing at all haha but with the fan and power supply being around $150 I'm willing to spend around $350 on the graphics card. The HD Radeon 6970 fits my budget perfectly, would that work?
Get the 6950 2gb version then flash it to the 6970.
For psu you can look for the Seasonic 520w its bang for buck
If a person can afford the 6970 outright, that is a better value than getting a 6950. Not only is the unlock not guaranteed to work (and may brick it besides), but a 6970 still outperforms the 6950 after its unlocking.
