you really need to give more information than that. the big one is spending limits. if you're limit is $1,000.00 then there are quite a few options for you. if its less than that you will slowly have less and less options the lower in price you go. so i am going to assume you wish to pay no more than 1000 before shipping and tax and all that. given that i can't just assume you'll spend that much I'll also list several other options at lower price (please note none of these require any assembly however you wont get as much performance for your buck.) #1 ibuypower build http://www.newegg.com/Product/Product.aspx?Item=N82E16883227283 Price:$749.99 Specs: Gaming AMD Phenom II X4 965(3.4GHz) 64 bit Quad-Core Processor 4GB DDR3 1333 1TB SATA Hard Drive 24X DL DVD+/-RW Drive ATI Radeon HD5670 1GB review: if you're looking for performance this is you're buy Whats Missing?: keyboard, mouse, monitor, operating system #2 AMD/ati build http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6970963&CatId=2846 Price: $649.99 Specs: AMD Athlon II X4 630 2.8GHz 4GB DDR3 500GB 7200RPM HDD 1GB AMD Radeon HD 6850 500W PSU DVDRW review: good performance slightly cheaper Whats missing?: keyboard, Mouse, Monitor, Operating system #3 ibuypower rig 2 http://www.newegg.com/Product/Product.aspx?Item=N82E16883227314 Price:$539.99 Specs: Gaming AMD Phenom II X4 925 (2.8GHz) 64 bit Quad-Core Processor 4GB (2GB x 2) DDR3 RAM 1TB Hard drive 24X DL DVD+/-RW Drive ATI Radeon HD 5570 1GB Review medium/low gaming rig will play most games on medium settings.

Whats missing?: keyboard mouse monitor ok so there are your options or at least the options i would go with at the various price levels. the prices were correct as of 6:26 pm PST 1/27/2011. all of these are missing a input system (keyboard, mouse) and monitor. a couple are missing any form of operating system. if you don't know how to install an os then don't buy the ones without one... hope that helps -Siege10
