I have the Dell XPS 435 MT and have had it for a few years now, needless to say it's getting a bit dated, I have already ordered a new power supply because the one the pc came with didn't leave any room for upgrades. The power supply is 600W and confirmed to work with my pc. Now I just need to pick out a Graphics card, I would like to have one that of course survive on 600W and also play the newest games like battlefield 3 and such. I don't want the best though, I'm trying not to spend to much money. It might also be helpful to get a ATI radeon graphics card since that is what I have now and have all the drivers for, but I'm not sure if it would be hard or not to install a Nvidia card or not so maybe you could help me there too.
8 GB of RAM
Intel Core I7 920 @ 2.7ghz
64 bit OS
Cut to the chase-
I need a new graphics card to run the newest games on the market, I have a 600W limit, I would prefer a ATI card, I'm on a budget.
