dude, it happens, it was a rare situation. i just happened to fry them on accident. some parts stopped working after a while too. i found that i have less problems with prebuilts. and look for yourself online, there is coupons without hundreds of dollars knocked off, plus you get a piece of mind, customer support is better with dell then having to rma a part to a company such as newegg. also, i just gave you a nice example that i had a thousand dollar knock off with a dual xeon system. so evidently your not paying attention and don't know what your talking about.
original poster: don't believe these guys, they obviously are not paying attention. and there's always the risk of frying a part. i know it might be rare but it happens, you get a peace of mind when you buy prebuilt, at least in my experience. as i said, your on the right track. also, games are graphics bound more then anything, so if you feel you have to upgrade your graphics in the future, then so be it. i really don't know what that guy is talking about not being able to upgrade, i mean how many things do you need to upgrade? your wasting money obviously.
