I have a HP Pavilion p7-1054, and I added an AMD Radeon HD 6450 about the time Skyrim came out. It has served me well, but I now want to upgrade to play games like Arkham Origins, Bioshock Infinity, and AC4.
I want to order it right away, and do not want to spend a ton of money with Christmas coming up. Approx $150-$200. The HP only has 6 GB of RAM, so if it would make sense to update that and go with a less powerful card, then I would do that.
The HP only has a 250W PS, so I think that might need an upgrade as well...
The other hurdle is that my monitor is only VGA. LG 19EN33. I can probably get an adapter for that, right?
