I have a fairly old PC that I built myself...Pentium 4, AGP video card. I picked up Fallout 3 and....well, you know the rest of the story. The lag nearly sent me into shock. I have this beautiful game that I can't play past Commodore 64 specs, and it's killing me. I get Maximum PC, and all the time I come across ads for PC vendors that build custom rigs. Since my machine is so dated, I've not kept up with the 'latest and greatest' in terms of CPU technology, GPU technology, etc. Can anyone recommend any of these 'third party' (I mean not HP/Dell/Gateway folks) manufacturers, or is it still cheaper to build your own rig? I don't have a whole ton of time on my hands, and I figured in this economy I could find a prebuilt system with tech support that would perform nicely and still wouldn't break the bank a la Alienware. My budget is in the $1200-1500 range, not including a monitor or printer. Suggestions?
