Since I think it's about time for me to get a better system, my current one is too crappy to be upgrade due to it being AGP. The current specs on it are Motherboard CPU= AMD Athlon 1800+ RAM= 1024mb Video Card= Radeon 9200 80 GB Hard Drive Could someone please put together a build that costs under 800$, and can handle source games and multiple other games on high/medium settings with good fps. I'm not looking for top of the line stuff. Just a good duo core processor, a good video card, that won't cost me a fortune. Now I'm not really good at building them, but I'm pretty sure that there are good sites to guide you through it, so I can give it a try, and if not I'll call the Geek Squad or something. Please include all the stuff I need because I don't want to find out that I need additional stuff when all of it arrived and I will have to wait another few days.
