Hi, Mike here. Currently I have an HD 6570. But now that I have a job, I'm trying to upgrade to either an HD 6670 or an HD 7750. My first question is, will these both work on a stock Dell 300w psu? That's my first question. Secondly, I know when you buy these graphics card there are different versions like Gigabyte, XFX, HIS and so on. Currently, I have an HIS HD 6570 with passive cooling and it tends to get very hot(Reaching up to around 80C-100C on intense games). Which version of these cards should I get if I want around 60C at max load?

Thanks. Now honestly though on 300w, will I be able to overclock it or not? I'm interested in knowing that. Also, which version will have the best cooling, the iCooler version or a fanless version with passive cooling? I just want to know, because I got an HD 6570 with passive cooling(Nothing but a heatsink) that would reach 100c.

If it helps, I was able to overclock my 6570 to 1000 mhz, with no significant problems, except for temperatures in heavy games.

Does it reach 100C in games, when you OC'd?
Turn it back into it's default clock speeds.

Only games like Mafia 2. Even at the stock clocks.

That's why I'm trying to make sure I get whatever version of the 7750 that has the best cooling. I'd be happy with around 60c for the max load and maybe 30c-50c idle. With OCing I'd even be happy with around 70c-80c but no higher.

Go for the HIS iCooler if that is available.
