If I consider purchasing an AIW x800xt, I think that upgrading the 512MB RAM on the system to 1GB would be a good idea, or am I wrong? Is purchasing that graphic card a good idea? I have a $180 - $200 budget.
Is the video card a good idea? First, we need to know what your current video card is. Next, we need to know the brand and specs of your PSU. Then we also need to know what games you want to play and at what settings.
My current video card is a Radeon 9000. At the moment I don't know what PSU (power supply unit if I'm not wrong, I'm Spanish) I have, but I think it'll give around 350W. I'd like it to play all kind of games, new and old without problem (Quake 4, Doom 3, Age of Empires 3, Pro Evolution 5, etc.). Settings 1280 x 1024, at high FPS and all effects enabled at medium or high if possible.
I have that card and it does the job well enough. 1GB will help allot as well with textures and the likes. Then you will need to upgrade your CPU to get more out of games. Then you will need a new motherboard to accept the new CPU. Then you will need a new case because it is making to much heat. Then you will need a power supply because you need more juice to overclock. Then you will need a new graphics card because you need to use shader version 11.9718765. What where we writing about?
I don't want to buy a crappy power supply, the one I saw on their webpage is the generic or basic one. Then there was a Thermaltek of 500W for 170€ (more or less $210) or 430W for $150, way too much for me. The one I have at the moment is FSP. I'll take note of what you've said.
