I would like to upgrade the graphics card. Ideally I would like to play Dragon Age and maybe COD4:MW2 at medium - high settings. In order to get a better graphics card I'm pretty sure I would need a new power supply since the one I have is only 400W. I've also been told that I should upgrade my CPU, but really I have no clue.
Really, all I want is to play modern games at medium to high settings. So if that entails just getting a better graphics card I'll do that. If I have to get a new power supply/CPU I'm willing to do that too.
As far as prices go I'd like to not spend more than 200 on a graphics card. I'd be willing to spend around 100 on the CPU.
You could get a ATI 4670 without changing that power supply for about $80.00.
I would ask Gateway what processors are supported.
You might need a bios update.
