I recently got the Dell Inspiron 660 and although I can play a lot of games with the integrated graphics it comes with, I would like to upgrade to a dedicated graphics card so I can play more modern titles. Reading around, I figured the 7750 is a popular card to run on 300w yet on the AMD website they recommend at least 400w. I'd just like to check before I buy it that it would work.
OS: Windows 8 64 bit
Processor: Intel Core i5 @3ghz (quad core)
RAM: 4gb (thinking about upgrading to 8gb)
PSU: 300w apparently (presume it's made by Dell)
