ok well first of all you need a computer with a good video card and a fast processor. a amd athlon or pentium specifically not a celeron because the celeron processors are the low end cheap ones for buget systems. you can get a good gamning computer from dell for around $1000 as for building your own you need to have vast knoweledge on how to put things together and how to troubleshoot and get things to work. putting your own together isn't good for a person who in my opnion isn't a good idea. i can't remember the name but there is a gamming computer that it's sold purpose is for gamming and it's a small box and they start at around $800 bucks you can do other things with them and you can install a larger hard drive, but don't count on upgrading the processor. good luck in you search it you want more information e-mail me.
I've been building computers for a long time now, about 5 - 6 years. However, I've always been disappointed in the performance of my built systems when it comes to hardcore gaming. For instance, I wasn't getting the FPS rates I was looking for; games were choppy and didn't have the "flow" that my friends were telling me about, and that I was reading in game reviews. Can anyone point me to a great system, that I don't have to get another mortgage to buy? Or can someone simply do a step-by-step build-your-own system spec list, showing me specifically what components (Motherboard, graphics card, memory, etc.) would be necessary so that I can play BF Vietname, UT2004, or EQ2 with FULL, MAXED OUT video settings without a choppy frame rate? I would be greatly appreciative. Also, if you want, include some educating material or info so that I can learn a little more about what makes a great system.
