Hi, I am wondering if you could add a Radeon HD 6870 into a PC with a 460W PSU. I've heard people saying that Dell PSU's are good, and that is what I have, so that could influence things. The other specs of PC are:
Intel Core i7 3770 - 3.4 GHz
8 GB Dual Channel 1600 MHz DDR3
Current GFX card is AMD Radeon 7570 1GB GDDR5
Not sure about motherboard or fans.
If you can't add one, could you recommend a card that would work? I read that that card could play most games on Ultra, so that is why I wanted it.
