Hi, I'm about to upgrade soon and was planning on getting the 7750HD i also saw that the 450gts was a similar price and similar performance, what do you think and if you have other recommendations please post it. I want to be able to play most games at 1920x1080. My budget is pretty strict too but i can manage to get some more if i need to. Also i'll grab a new PSU for that graphics card so any good brands too?
