I have to agree with Archie. Most pre-built systems are already a year or so old and definitely way behind with graphics cards.
Case in point:
I went to purchase an Alienware thru Dell. I loved the system but even with Alienware you don't get what you pay for. The cards are behind and just on the edge of playability with these newer graphic intensive games. I decided against it because I just couldn't get the thing configured for a reasonable price. And then they throw 400 worth of tax on it at the end. Nice!
NewEgg or TigerDirect are two good places to build systems. They also have really cheap barebone systems that you have to put together yourself. Not really that hard once you get past the heatsink on the chip.
I am really glad that this subject came up because I wanted to ask the same question but on a more precise level.
What is a GOOD system to own right now for gaming, moding, and making movies. Something that is going to render fast. I probably just need a new card. Somebody recommend a good graphics card. Are the workstation graphics cards good for modding? The Quatro for example?
I really have a good asus board that I don't want to part with yet so I will probably just upgrade the memory and the graphics card.
Any help would be appreciated....
