I am currently in Iraq with the US Marine Corps so i don't have the ability to go to tech stores and get the latest word on new hardware from my friends and aquaintances back home. With the new quad core processors, new RAM and not to mention the graphics card technology progressing i don't know if i will be up to par enough to build my own rig when i get back to the states. I really am between a rock and a hard place. I am open to any suggestions and would like to hear your pros and cons on the matter!
