I have an onboard VGA on my mobo (take a look at my specs) and I wanna upgrade to a real VGA but I don't wanna spend a fortune because I am just a casual gamer, I only play games like 2 times a week because of work and stuff. I found these 2 cards which look great: HD 5670 and HD 5770 but I donno which one to get. I donno if there is a noticeable difference between these two. Games I wanna play on high settings (without/with little AA) are: Call of duty black ops, fallout new vegas, gta 4 and whatever good game is. Max resolution of my monitor is 1600x1200. Also, I have a Gigabyte brand 500W PSU with only 1 PCI express connector. Will it be enough? I don't wanna upgrade PSU ATM. Any suggestions? I'd appreciate any other card recommendations. Thanks, Josh EDIT: I also came across the HD 5750 and looks like I can afford it. SO?
