I've built computers before, nothing super fancy or anything with the help of some of my male friends. I thought it was about time I built my first semi-decent rig. I mostly looking for cost, I want to get the best bang for my buck. I just need something to tie me down for a few, considering this is my first time building a rig like this. I want basically what all gamers want, I play a lot of MMPORG's and Online Games, so I need speed, I can't deal with lag or choppy video card refresh rates, so I need something decent. Right now I was looking into : Asus K8N Deluxe Athlon 64 DDR400 Mobo - 754 pin - 120$ (cheaper then going 939pin, and I don't plan on upgrading this project) Enermax PSU 370w - 50$ I don't know what kind of CPU yet, not very familiar with them, so that will be my first question, of course it will be a 754 pin. I know I was kinda leaning towards the - Athlon 64 3000 Barton its 462 pins. Will it fit on a 754 pin board? Also how good is the proc? any better priced ones or speed let me know. Any help will be oblidged. Next, I heard that since I'm going Asus Mobo I need to stick with Corsair RAM, and of course a dual pack of it to take use of the DDR function. If this is true or not again any help would be appreciated. Next is the video card, again I play MMPORGS and Online games I also tend to do some Graphics and the works so I need something decent, yet powerful. Now cooling I heard that for the CPU Thermaltake Fan's do pretty good is this true? Also for a case? Should I go Aluminum? or What? Big Tower small Tower? mainly for Cooling. Harddrive also is a good question, but I don't really want to ask any now, I need to continue reading and researching them, but if you can what are some of the MAIN things I should look for in a HD. Thanks for all the help.
