Bought a Advent-DT1411 (Specs: Motherboard - Foxconn H61MXL/H61MXL-K. Graphics Card - AMD HD6670 2GB GDDR3. Processor - Intel i5-2320 @3.0Ghz.) not long ago, but I want to put in a newer graphics card I was thinking of getting a GTX660 or a GTX650, I could do with something in between that price range. Also I'm not sure if those graphics cards would work, I think I would need a better PSU, I think my current is a 400W but I'm not sure how Id check. If anyone could recommend me a good graphics card that would work with my current PC it would be really helpful, Thanks!
